Isolated delayed metastasis to the talus from Ewing`s sarcoma by Layla Nasr et al.

Published: 2018 Aug
Issue: 12(8) :: Pages: 17-24


Free full text article: Isolated delayed metastasis to the talus  from Ewing`s sarcoma

Fulltext article    PDF fulltext

Abstract: Bone metastasis to the hands and feet, known as acrometastasis, is a very rare finding and tends to be associated with extensive metastasis. We herein report the case of a 14-year-old girl known to have a history of successfully treated Ewing`s sarcoma arising from the ribs, who presented with a pathologically proven isolated metastatic lesion to the talus 7 years after achieving clinical and radiologic remission. We describe the imaging findings on MRI, CT scan and PET-CT. To our knowledge, talar metastasis from Ewing`s sarcoma has been previously reported only twice in the English literature. Noteworthy is the fact that one of the previously reported lesions was considered a skip metastasis, and the other was under-described in terms of primary and secondary tumor location and time to metastasis. In addition, the overall imaging findings were rather suggestive of a benign lesion, particularly on CT scan.

Issue: 12(7) :: Pages: 16-24


Free full text article: Aneurysmal bone cyst of the frontal bone -  A radiologic-pathologic correlation

Fulltext article    PDF fulltext

Abstract: We present a case of 27-year-old female who presented for a progressive frontal swelling with ipsilateral headache. Subsequent CT scan revealed an extradural and expansile multiloculated mass with thin and strongly enhanced septations and MRI evaluation showed internal hyperintensity on T2 with no restriction of diffusion and confirmed the multiple cystic spaces with enhancing septations and rare hemorrhagic fluid-fluid levels. Surgery was performed and diagnosis of aneurysmal bone cyst was made on frozen section. Identification of USP6 fusion gene by in situ hybridization technique permitted to confirm the diagnosis of primary ABC. Although aneurysmal bone cyst (ABC) of the skull is a very rare entity and accounts for 2-6% of all ABCs, we should think about it in front of osteolytic and cystic skull changes even with very few fluid-fluid levels. Following description of our case and differential diagnoses, we conduct a literature review of skull ABCs imaging characteristics and discuss the interest of USP6 rearrangement identification.

Glenohumeral Joint Sepsis after Joint Injection through a New Tattoo by Richard Becker et al.

Published: 2017 Nov
Issue: 11(11) :: Pages: 28-35


Free full text article: Glenohumeral Joint Sepsis after Joint Injection through a New Tattoo

Fulltext article    PDF fulltext

Abstract: We report a case of Propionibacterium acnes septic arthritis of a shoulder following two joint access procedures. Methodical investigation of these two procedures was performed using the Joint Commission root cause analysis matrix, which involved examination of protocols, interviews with technologists and physicians, and inspection of the procedure rooms and equipment. No procedural error or other causal factor for infection was found other than the injection through a five day-old tattoo during the first procedure. We could find no other reported cases of Propionibacterium acnes seeding a joint via an arthrogram needle. This may be an under-reported phenomenon or could be a unique case. In either instance, the occurrence bears notice by anyone performing joint access procedures.

That`s my STYLEoideum - Symptomatic os styloideum in an adolescent male by Malwina Kaniewska et al.

Published: 2017 Jul
Issue: 11(7) :: Pages: 14-19


Free full text article: That`s my STYLEoideum -  Symptomatic os styloideum in an adolescent male

Fulltext article    PDF fulltext

Abstract: We present a 15-year-old male patient with persistent localized pain on the dorsal side of the left wrist between the base of the 2nd and 3rd metacarpal bones and over the third carpometacarpal joint. It was diagnosed as an accessory metacarpal bone -Os styloideum. This entity may be detected on plain radiographs and in ultrasound examination and is often asymptomatic. Symptomatic os styloideum occurs more frequently in the dominant hand and may be treated conservatively with corticosteroid infiltration. A palpable prominence on the dorsal side of the wrist and focal pain evoked anxiety of the adolescent patient who searched medical consultation. In the clinical examination, a bony protrusion was confirmed and different possible diagnoses have been considered. After treatment with a corticosteroid infiltration of the third carpometacarpal joint under fluoroscopy the pain resolved completely. We would like to draw attention of clinicians and radiologists to this rare anatomical variant that normally is asymptomatic, and therefore not immediately recognized. Acquaintance with this entity and its early detection may lead to conservative treatment instead of surgical excision. A comprehensive literature search, review and discussion about os styloideum are provided in the article.

A pictorial review of reconstructive foot and ankle surgery: evaluation and intervention of the flatfoot deformity by Andrew J Meyr et al.

Published: 2017 Jun
Issue: 11(6) :: Pages: 26-36


Free full text article: A pictorial review of reconstructive foot and ankle surgery: evaluation and intervention of the flatfoot deformity

Fulltext article    PDF fulltext

Abstract: This pictorial review focuses on basic procedures performed within the field of podiatric surgery, specifically for elective reconstruction of the midfoot and rearfoot with focus on the flatfoot deformity. Our goal is to demonstrate objective radiographic parameters that surgeons utilize to initially define the deformity, lead to procedure selection, and judge post-operative outcomes. We hope that radiologists will employ this information to improve their assessment of post-operative radiographs following reconstructive foot surgeries. First, relevant radiographic measurements are defined and their role in procedure selection explained. Second, the specific surgical procedures of the Evans calcaneal osteotomy, medial calcaneal slide osteotomy, Cotton osteotomy, subtalar joint arthroeresis, and arthrodeses of the rearfoot are described. Finally, specific plain film radiographic findings that judge post-operative outcomes for each procedure are detailed.

Issue: 11(5) :: Pages: 13-26


Free full text article: Correction of Grade 2 Spondylolisthesis Following a Non-Surgical Structural Spinal Rehabilitation Protocol Using Lumbar Traction: A Case Study and Selective Review of Literature

Fulltext article    PDF fulltext

Abstract: Objective: Discuss the use of non-surgical spinal rehabilitation protocol in the case of a 69-year-old female with a grade 2 spondylolisthesis. A selective literature review and discussion are provided. Clinical Features: A 69-year-old female presented with moderate low back pain (7/10 pain) and severe leg cramping (7/10 pain). Initial lateral lumbar x-ray revealed a grade 2 spondylolisthesis at L4-L5 measuring 13.3 mm. Interventions and Outcomes: The patient completed 60 sessions of Mirror Image® spinal exercises, adjustments, and traction over 45 weeks. Post-treatment lateral lumbar x-ray showed a decrease in translation of L4-L5 from 13.3 mm to 2.4 mm, within normal limits. Conclusions: This case provides the first documented evidence of a non-surgical or chiropractic treatment, specifically Chiropractic BioPhysics®, protocols of lumbar spondylolisthesis where spinal alignment was corrected. Additional research is needed to investigate the clinical implications and treatment methods.

Radiologic Findings in Gabapentin-Induced Myositis by Tyler Michael Coupal et al.

Published: 2017 Apr
Issue: 11(4) :: Pages: 30-37


Free full text article: Radiologic Findings in Gabapentin-Induced Myositis

Fulltext article    PDF fulltext

Abstract: Throughout recent years, Gabapentin has become increasingly used for the treatment of neuropathic pain. We report on a case of a 31 year old female who presented to the emergency department with unilateral leg pain, weakness, and swelling after increasingly titrating her Gabapentin dosage over three weeks. Magnetic resonance imaging confirmed the presence of myositis confined to the left thigh and the patient`s symptoms and laboratory abnormalities resolved following Gabapentin cessation. While Gabapentin-induced myositis and rhabdomyolysis is a rare entity, it should be a diagnostic consideration for radiologists, particularly in the absence of infection or trauma.

Free full text article: A pictorial review of reconstructive foot and ankle surgery: elective lesser forefoot procedures

Fulltext article    PDF fulltext

Abstract: This pictorial review focuses on basic procedures performed within the field of podiatric surgery, specifically for elective procedures of the lesser forefoot including the correction of hammertoes and lesser metatarsal deformities. Our goal is to demonstrate objective radiographic parameters that surgeons utilize to initially define the deformity, lead to procedure selection and judge post-operative outcomes. We hope that radiologists will employ this information to improve their assessment of post-operative radiographs following reconstructive foot surgeries. First, relevant radiographic measurements are defined and their role in procedure selection explained. Second, the specific surgical procedures of the digital arthroplasty, digital arthrodesis, lesser metatarsal osteotomy, and correction of metatarsus adductus are described in detail. Finally, specific plain film radiographic findings that judge post-operative outcomes for each procedure are detailed.

Persistent proatlas with additional segmentation of the craniovertebral junction - The Tsuang-Goehmann-Malformation by Holger Spittank et al.

Published: 2016 Oct
Issue: 10(10) :: Pages: 15-23


Free full text article: Persistent proatlas with additional segmentation of the craniovertebral junction - The Tsuang-Goehmann-Malformation

Fulltext article    PDF fulltext

Abstract: Case study description and analysis of a complex craniovertebral dysplasia in an 8-year-old male patient, in which conventional cervical spine radiographs demonstrated a regularly differentiated occipital base, as well as the presence of two lateral masses of the proatlas vertebra and two lateral masses of the atlas vertebra. Further assessment included computed tomography of the occipital base and the upper cervical spine as well as three-dimensional reconstruction. Malsegmentation of the fourth occipital vertebra can result in various anomalies that are known as `manifestation of the proatlas`. The occurrence of a persistent proatlas with additional segmentation of the craniovertebral junction represents an extremely rare dysplasia. To our knowledge, it is the second report concerning the persistence of a complete human proatlas vertebra. We consider the biomechanical and embryological particularities of this complex dysplasia to represent sufficient basis for future differentiation from other malformations of the fourth occipital vertebra. Comprehensive literature review and discussion about the entity will be provided.

Impact of Isometric Contraction of Anterior Cervical Muscles on Cervical Lordosis by Curtis A Fedorchuk et al.

Published: 2016 Sep
Issue: 10(9) :: Pages: 13-25


Free full text article: Impact of Isometric Contraction of Anterior Cervical Muscles on Cervical Lordosis

Fulltext article    PDF fulltext

Abstract: Objective: This study investigates the impact of isometric contraction of anterior cervical muscles on cervical lordosis. Methods: 29 volunteers were randomly assigned to an anterior head translation (n=15) or anterior head flexion (n=14) group. Resting neutral lateral cervical x-rays were compared to x-rays of sustained isometric contraction of the anterior cervical muscles producing anterior head translation or anterior head flexion. Results: Paired sample t-tests indicate no significant difference between pre and post anterior head translation or anterior head flexion. Analysis of variance suggests that gender and peak force were not associated with change in cervical lordosis. Chamberlain`s to atlas plane line angle difference was significantly associated with cervical lordosis difference during anterior head translation (p=0.01). Conclusion: This study shows no evidence that hypertonicity, as seen in muscle spasms, of the muscles responsible for anterior head translation and anterior head flexion have a significant impact on cervical lordosis.

Multiple hereditary exostoses: A pseudoaneurysm masquerading as tumor by Hari Trivedi et al.

Published: 2016 Aug
Issue: 10(8) :: Pages: 50-59


Free full text article: Multiple hereditary exostoses:  A pseudoaneurysm masquerading as tumor

Fulltext article    PDF fulltext

Abstract: Multiple hereditary exostoses is an autosomal dominant condition characterized by numerous benign osteochondromas. Complications are rare and can include deformity, growth abnormality, fracture, adventitial bursa formation, local mass effect on a nerve, malignant degeneration, and vascular complications including stenosis, occlusion, arteriovenous fistula, and pseudoaneurysm. We present a case of multiple hereditary exostoses leading to a deep femoral artery pseudoaneurysm in the proximal medial thigh with subsequent rupture and hematoma, masquerading as tumor.

Delayed Presentation of a Chronic Morel-Lavallée Lesion by David Christian et al.

Published: 2016 Jul
Issue: 10(7) :: Pages: 30-39


Free full text article: Delayed Presentation of a  Chronic Morel-Lavallée Lesion

Fulltext article    PDF fulltext

Abstract: Morel-Lavellée lesions are soft tissue degloving injuries resulting from shearing trauma that induces separation of the superficial and deep fascias creating a potential space that becomes filled with hemolymph. Here we present a case of a 28-year-old male presenting with a persistent Type I Morel-Lavallée lesion 2.5 years after an automobile versus pedestrian accident. These lesions can be visualized via computed tomography, plain film and ultrasound, but magnetic resonance imaging is the modality of choice for their identification and characterization.

Free full text article: Intra-articular osteoid osteoma at the femoral trochlea treated with osteochondral autograft transplantation

Fulltext article    PDF fulltext

Abstract: We present the case of an intra-articular osteoid osteoma at the femoral trochlea. Intra-articular osteoid osteoma can present a diagnostic challenge both clinically and with imaging because it presents differently from the classic cortical osteoid osteoma. Given the lesion’s proximity to overlying cartilage, the patient underwent resection of the lesion with osteochondral autograft transplantation at the surgical defect. A comprehensive literature review and discussion of intra-articular osteoma will be provided.

Fulltext article    PDF fulltext

Abstract: Isolated injuries to the teres major muscle occur in competitive sporting activities such as baseball pitching, hockey and tennis. We report a similar event of a physically fit man sustaining an isolated teres major rupture while waterskiing. Non-operative management was chosen, with pain resolution and no appreciable functional limitations at follow up. Because teres major muscle injury was suspected at the time of imaging, we present a dedicated imaging protocol to optimize assessment for teres major injury.

Free full text article: Incidental Anterior Cruciate Ligament Calcification: Case Report

Fulltext article    PDF fulltext

Abstract: The calcification of knee ligaments is a finding noted only in a handful of case reports. The finding of an anterior cruciate ligament calcification has been reported once in the literature. Comparable studies involving the posterior cruciate ligament, medial collateral ligament and an ossicle within the anterior cruciate ligament are likewise discussed in reports of symptomatic patients. We report a case of incidentally discovered anterior cruciate ligament calcification. We discuss the likely etiology and clinical implications of this finding.

Free full text article: Apparent diffusion coefficient map of a case of extramedullary plasmacytoma

Fulltext article    PDF fulltext

Abstract: Plasmacytomas are rare tumors, which arise from the monoclonal proliferation of malignant plasma cells. They may affect either the bony skeleton or rarely the soft tissues, the latter being referred to as extramedullary or extraosseous. We report a case of an extramedullary plasmacytoma that presented as a soft tissue mass involving the muscles of the left leg, in a patient who was previously treated for multiple myeloma. We describe the MR Imaging characteristics of the tumor and highlight the usefulness of diffusion-weighted imaging with apparent diffusion coefficient mapping.

Evolution of gout: "malignant" change over time? by Sterling Ellis Eide et al.

Published: 2015 Oct
Issue: 9(10) :: Pages: 35-46


Free full text article: Evolution of gout:

Fulltext article    PDF fulltext

Abstract: Gout is a common entity; yet it is such a great mimicker in its imaging features that it can confuse clinicians and radiologists alike, sometimes leading to unnecessary investigations and treatment. We present a case of a 52 year old male renal transplant patient who presented with a slow growing mass in his left shin. The initial radiograph demonstrated a non-aggressive looking calcified lesion. A fine needle aspiration demonstrated this lesion to be gout deposition. The lesion was unchanged in the following eight years until the patient reported a sudden growth in size. Imaging showed features of an aggressive lesion with disruption of the previous calcification as well as enhancement on magnetic resonance imaging. Surgical excision biopsy was performed in view of the worrisome features on imaging and the histology showed tophaceous gout. Following description of our case, we reviewed the clinical and imaging features of gout and discussed its differential diagnoses.

Mycobacterium kansasii causing chronic monoarticular synovitis in a patient with HIV/AIDS by Leo Menashe et al.

Published: 2015 Sep
Issue: 9(9) :: Pages: 26-35


Free full text article: Mycobacterium kansasii causing chronic monoarticular synovitis in a patient with HIV/AIDS

Fulltext article    PDF fulltext

Abstract: Mycobacterium kansasii is a nontuberculous mycobacterium that primarily causes pulmonary disease in AIDS patients, however it has also been known, rarely, to result in skeletal infection. When skeletal infection occurs, the time from onset of symptoms to diagnosis is up to 5 years in previously reported cases. We describe a 48-year-old woman with HIV/AIDS who presented with chronic, isolated left knee pain and swelling of over two decades which had recently worsened. Radiographs and magnetic resonance imaging demonstrated marked subarticular erosions, synovial thickening, and bone marrow edema, which had progressed compared with prior imaging done seven years earlier. Synovial biopsy grew Mycobacterium kansasii. Following the presentation of our case, clinical and imaging findings, including the differential diagnosis, of monoarticular arthritis caused by Mycobacterium kansasii are reviewed and discussed.

Abstract: Sarcoidosis is an idiopathic inflammatory disorder characterized by the presence of non-caseating tissue granulomas most commonly affecting lungs, lymph nodes and skin. Sarcoid skeletal involvement is relatively uncommon and in particular tenosynovitis. We describe an unusual case of sarcoidosis presenting with granulomatous tenosynovitis as the only manifestation of the disease, illustrating the radiological findings on different modalities followed by a review of the literature. Radiologists and clinicians should be aware of tenosynovitis as a manifestation of sarcoidosis as early and therefore appropriate treatment significantly alters patient`s outcome and prognosis.

Abstract: This pictorial review focuses on basic procedures performed within the field of podiatric surgery, specifically for the hallux abductovalgus or "bunion" deformity. Our goal is to define objective radiographic parameters that surgeons utilize to initially define deformity, lead to procedure selection and judge post-operative outcomes. We hope that radiologists will employ this information to improve their assessment of post-operative radiographs following reconstructive foot surgeries. First, relevant radiographic measurements are defined and their role in procedure selection explained. Second, the specific surgical procedures of the distal metatarsal, metatarsal shaft, metatarsal base, and phalangeal osteotomies are described in detail. Additional explanations of arthrodesis of the first metatarsal-phalangeal and metatarsal-cuneiform joints are also provided. Finally, specific plain film radiographic findings that judge post-operative outcomes for each procedure are detailed.

Abstract: Insertion of the peroneus brevis tendon normally occurs at the lateral aspect of the fifth metatarsal base. However, there is new evidence that congenital variant insertion of the tendon on the calcaneal peroneal tubercle occurs in a small segment of the population. We report a case of 24-year old male presenting with non-traumatic ankle pain who underwent ankle magnetic resonance imaging. Imaging demonstrated insertion of the peroneus brevis tendon on the calcaneal peroneal tubercle with absence of the tendon distal to the calcaneus. Furthermore, in reviewing 200 consecutive ankle magnetic resonance examinations, the authors discovered one additional case of this variant. We discuss the magnetic resonance imaging characteristics of this anatomic variant, the implications for clinical management, and review the literature on peroneal anatomic variations.

Abstract: We report a case of posterior hoffitis in a middle-aged woman with no prior history of significant major trauma. Her symptoms of anterior knee pain and limited extension failed conservative measures. Preoperative magnetic resonance imaging demonstrated a significantly thickened infrapatellar plica tethering Hoffa`s fat pad in the anterior interval of the knee. Arthroscopic resection of the infrapatellar plica resulted in complete resolution of symptoms within six months following the surgery.

Synovial sarcoma of the abdominal wall: Imaging findings and review of the literature by Robbert J. de Haas et al.

Published: 2015 Feb
Issue: 9(2) :: Pages: 24-30


Free full text article: Synovial sarcoma of the abdominal wall: Imaging findings and review of the literature

Fulltext article    PDF fulltext

Abstract: Synovial sarcoma is the fourth most common type of soft-tissue sarcoma (following undifferentiated pleomorphic sarcoma, liposarcoma, and rhabdomyosarcoma), and should be considered a high-grade neoplasm with a high number of local recurrences and late metastases. Synovial sarcoma predominantly occurs in adolescents and young adults, and typically arises near the joints of the lower extremity. However, this tumor can also occur at uncommon sites such as the abdominal wall, which is illustrated in this article. Furthermore, we reviewed the available literatures on the clinical, pathological and radiological appearances, as well as the current knowledge concerning treatment options and prognosis.

Abstract: Soft tissue aneurysmal bone cyst is a rare entity, with about 20 cases reported in literature, only 3 of which are in patients over 40 years of age. We present a case of a 41 year old Latin American female who presented for evaluation of atraumatic chest pain with radiation to the left shoulder. Her initial workup was negative, including radiographic imaging of the chest and left shoulder. 4 months later, she presented to her orthopedic surgeon with a palpable mass and mild left shoulder pain. Radiographs acquired at that time demonstrated a 7.0 x 5.5 x 6.7 cm mass with rim calcification in the region of the upper triceps muscle. Subsequent CT imaging showed central areas of hypodensity and thin septations, a few of which were calcified. MR evaluation showed hemorrhagic cystic spaces with multiple fluid-fluid levels and enhancing septations. Surgical biopsy was performed and pathology was preliminarily interpreted as cystic myositis ossificans, however on final review the diagnosis of soft tissue aneurysmal bone cyst was made. The lesion was then surgically excised and no evidence of recurrence was seen on a 3 year post-op radiograph. Following description of our case, we conduct a literature review of the imaging characteristics, diagnosis, and treatment of soft tissue aneurysmal bone cyst.

Fulltext article    PDF fulltext

Abstract: Discal cysts are extradural masses that communicate with the intervertebral disk and are a rare cause of lower back pain and lumbar radiculopathy. This case report describes a lumbar discal cyst, the diagnosis of which was confirmed on conventional discography, and which was treated with computed tomography-guided aspiration and steroid injection. Several reports have described this procedure, but only one in the radiology literature, and thus the purpose of this report is to remind the radiology community of the existence of this entity and propose a minimally invasive means of treatment.

Abstract: Congenital indifference to pain is a rare and debilitating congenital disease. Individuals with the disorder may have one or a combination of sensory or autonomic deficits, which can range from lack of mechanical nociception, diminished ability to detect heat and cool stimulation, to the devastating and fatal form which includes autonomic dysfunction. It is important for radiologists to be able to recognize the radiographic presentations of this rare disorder, as delay in diagnosis can lead to extensive and sometimes unnecessary workup. We present a case of congenital indifference to pain initially interpreted as a mass of the distal femur.

Abstract: A retrospective case series of three patients with chronic low back pain who received baseline MRI scans revealing multifidus muscle atrophy with fatty replacement is provided. Each patient received spinal manipulative therapy, and two were compliant with low back exercises targeting the multifidus. A follow-up scan performed >1 year later was compared to the baseline scan revealing a decrease in atrophy with fatty replacement in the two patients who performed multifidus-focused low back exercises (15% and 39% on the left and 7% and 32% on the right respectively), and an increase in the patient who underwent spinal manipulation alone (41% and 53%). Interestingly, the decrease in atrophy in the two patients that performed the exercises correlated to functional improvements. Though limited, these results highlight the utility of MRI in quantifying positive and negative long-term changes in multifidus atrophy, which may be an indicator of recovery in chronic low back pain patients.

Abstract: Although the clinical features of gluteus maximus contracture syndrome have been frequently described, imaging features have been seldom described. Most commonly reported cases are those following intramuscular injection in the gluteal region although congenital contracture is an uncommon but important occurrence. This condition has most often been reported in children of school going age. These patients often present with difficulty in squatting, limitation of hip motion or specific deformities and often require surgical correction. We describe the plain radiography, ultrasonography (USG) and magnetic resonance imaging (MRI) features of this condition in a patient with no previous known history of intramuscular injections.

Fulltext article    PDF fulltext

Abstract: Intraosseous pneumatocyst is a gas containing lesion located within a bone. It is a relatively rare condition of unclear etiology and with an undetermined natural course. Gas-density-fluid level pneumatocyst is even rarer. Pneumatocyst is frequently seen in adults but rarely reported in pediatrics. The lesion is usually small and is seen in the vertebral bodies as well as around the sacroiliac joints. Rarely does it occur in other parts of the skeleton. We are reporting a case of large blood signal intensity containing intraosseous pneumatocyst in a 14 year old boy and reviewing other pediatric cases of pneumatocysts as well as those with gas-density-fluid level. The recognition of this incidental rare benign lesion is essential to avoid over investigation and an inappropriate aggressive intervention.

Fulltext article    PDF fulltext

Interactive Image Stack

Abstract: Heterotopic ossification is a benign process of mature laminar bone formation in the soft tissues. A synonymous term used to describe this pathology in muscle is myositis ossificans. The pathogenesis is unclear, but is likely multifactorial. The basic pathology is thought to be ectopic production of osseous tissue as part of a repair process in response to tissue injury. This report describes a case of heterotopic ossification of the quadratus lumborum muscle as an incidental finding. This case highlights that treatment is based on symptoms and conservative management might be appropriate for the asymptomatic patient.

Abstract: While drug-related periostitis has been known of for many years, the specific association of diffuse periostitis with voriconazole (most frequently in transplant patients) has only been recently explicitly addressed in the literature. Recognition of the radiologic and clinical manifestations of voriconazole-related periostitis is important for helping to narrow an otherwise broad differential diagnosis. We present two cases that illustrate different radiologic presentations of this painful cause of diffuse periostitis. Case 1 features a 60 year-old woman with a history of orthotopic heart transplant who was hospitalized for "full body pain" with progressively worsening bone tenderness involving the humeri, knees, femurs, hips, and hands. Case 2 describes a 48 year-old man with a history of acute lymphoblastic leukemia status post stem cell transplant who presented with diffuse arthralgias involving bilateral ankles, knees, wrists, and elbows.

Fulltext article    PDF fulltext

Abstract: We report a case of a 56-year old man with chronic pain in both knees for several years. This patient had already undergone surgery on his left knee in 2002 after an x-ray showed multiple lytic and well margined lesions in the distal femur and proximal tibia with ground-glass matrix, involving Hoffa`s fat pad and the patellar ligament. Histology was consistent with an enchondroma. The most recent MRI examination showed enchondromatosis involving both knees with bilateral extension into Hoffa`s fat pad and the patellar ligament. Subsequently, we performed an additional radiographic examination of the hands and feet, as well as an MRI of both hands to identify other possible enchondromas in the most common sites for this disease. Enchondromatosis with soft tissue involvement is extremely rare, and involvement of Hoffa`s fat pad has not been reported in the scientific literature. The clinical presentation of this case and the general aspects of Enchondromatosis are discussed.

Abstract: Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor most commonly occurring in children, adolescents, and young adults. Clinically and radiographically the lesion is easily confused with a hematoma, soft tissue hemangioma, or malignant fibrous histiocytoma. While the lesion is rare, due to the potential for local recurrence and metastasis, it is imperative to consider this lesion in the differential diagnosis of a soft tissue mass in a child or adolescent. Here, we present the clinical, radiologic, and pathologic findings of a case of AFH.

Abstract: The peroneocalcaneus internus (PCI) is a rare accessory muscle of the medial ankle with typical MRI anatomic features allowing differentiation from the more common accessory flexor digitorum longus muscle. To our knowledge, there have been no previously published sonographic images of the peroneocalcaneus internus. A PCI is typically an incidental, asymptomatic finding, but knowledge of the entity may avoid confusion when initially encountered by diagnostic ultrasound. We review the anatomic imaging features which allow for a confident imaging diagnosis and the clinical relevance of this anomaly.

Abstract: Neonatal onset multisystem inflammatory disease (NOMID) is a rare autoinflammatory disorder, which manifests early in infancy. We describe a case of a 10-year-old boy who has been unwell since infancy. He presented with urticarial rash, intermittent fever and hepatosplenomegaly followed by progressive arthropathy. His joint symptoms started at two years of age, which progressively involved multiple joints, resulting in bone and joint deformities. A series of joint radiographs demonstrated bizarre enlarging physeal mass with heterogenous calcification. Magnetic resonance imaging (MRI) of the involved right ankle and knee showed characteristic thickened and calcified physeal lesions, which enhanced post-gadolinium. This debilitating disease is also known to involve the central nervous system and eyes. This case report aims to highlight the conventional radiographic and magnetic resonance imaging (MRI) findings of this physeal abnormality in NOMID syndrome.

Abstract: We describe a case of mixed liposarcoma of the axilla presenting as a high grade undifferentiated sarcoma with areas of well-differentiated and myxoid liposarcoma. MRI demonstrated a lobulated, septated intermuscular mass with marked heterogeneous gadolinium enhancement. A small focus of the tumor demonstrated fat suppressed signal more characteristic of well-differentiated liposarcoma. Pathologic analysis following wide local excision revealed a large, high grade sarcomatous component with highly pleomorphic cells with a thin rim of well-differentiated and myxoid liposarcoma on histologic examination. Dedifferentiated liposarcomas arising outside of the retroperitoneum are very rare, as are dedifferentiated liposarcomas arising from a histologically mixed liposarcoma. In this regard, this case illustrates an unusual combination of tumor location and histology which, to our knowledge, has not previously been reported.

Abstract: A 23 year old Asian female presented with swelling of right knee joint for 5 years with history of exacerbations and remissions of symptoms. She was initially diagnosed as a case of suprapatellar bursitis based on clinical and X-ray findings. Further evaluation with higher imaging modalities was pathognomonic of lipoma arborescens. Patient underwent synovectomy and the diagnosis was confirmed histologically. We describe a histologically proven case of lipoma arborescens to highlight the imaging findings on X-ray, Ultrasound and Magnetic resonance imaging with arthroscopic correlation. The unique feature of this case report is multimodality imaging correlation with arthroscopy and histopathology findings. We have highlighted the pathognomonic imaging findings of this rare but benign intra-articular lesion and also discussed the differential diagnosis in detail.

Abstract: The external snapping hip syndrome is a condition characterized by palpable or audible snap on the lateral region of the hip occurring during movements and sometimes associated with pain. It is typical of young adults and athletes and can be favored by the abnormal sliding of the iliotibial band or of the gluteus maximus muscle over the greater trochanter. We present a case of external snapping hip syndrome occurring in a young woman secondary to a dysmorphic sickle-shaped myotendinous junction of the gluteus maximus muscle. Diagnosis was allowed by an integrated clinical and radiological approach, based on dynamic ultrasound and magnetic resonance imaging (MRI).

Abstract: Keloids are defined as excessive scar tissue formation extending beyond the area of the original skin injury and occurring in predisposed individuals. While no single treatment has proven widely effective, several series report excellent outcomes for keloids with post-surgery radiation therapy as described in the literature. We present a patient with recurrent giant keloid of left buttock after several surgical removals, that at physical examination shows the size of 40x22x10 cm in the largest dimension. Patient underwent a surgical excision of gluteal lesion and postoperative radiotherapy using photons at 8 MV of linear accelerator: the total dose delivered was 22 Gy in 11 days, with a daily fraction of 2 Gy. No relapse was showed at 36 months post-therapy. Several methods seem unsatisfactory for preventing keloid recurrence. The combination of surgery and adjuvant radiotherapy seems an excellent strategy to prevent recurrent disease.

Interestingly, there was significant mass effect on the clivus, with clivus erosion and destruction, a finding that has not previously been described with this syndrome. The clinical and radiological characteristics of Crowned Dens syndrome, as well as CPPD are reviewed. We suggest that CPPD crowned dens syndrome may be included in the differential diagnosis when clivus destruction or erosion, in association with a soft tissue mass with calcification, is seen.

Fulltext article    PDF fulltext

Abstract: Sesamoid ossicles are ovoid or round nodular small bones found usually within a joint or tendon of the upper and lower limb and rarely at other regions. They are usually asymptomatic, resulting in an increased propensity to injuries. We report on two cases where sesamoid ossicles were detected within the nuchal ligament. The first one was a 55-years-old Caucasian male office employee, complaining of chronic pain in the cervical spine region accompanied by numbness of the left upper limb. During the routine lateral X-ray imaging two sesamoid ossicles were found within the nuchal ligament at the C4 and C5 spinous processes level. The second case was a 64-years-old Caucasian female store employee, complaining of chronic cervical spine pain. The routine lateral X-ray exhibited two sesamoid ossicles within the nuchal ligament at the C5 and C6 spinous processes level. Sesamoid ossicles found in the nuchal ligament in rare cases may become symptomatic and the pathogenesis mechanism should be differentially diagnosed by the physician. We discuss the precise morphology of the trait, the possible etiological mechanisms for their appearance, the histological features, as well as differential diagnosis.

Abstract: Rheumatoid arthritis (RA) leads to a progressive weakening of the skeleton which may result in bone fractures. However, spontaneous fractures (exclusive of stress fractures, vertebral collapse, and superficial articular fragmentation) in patients with rheumatoid arthritis have been only occasionally reported in the medical literature. A case of spontaneous talar and calcaneal fracture in rheumatoid arthritis is described. Bone lesions were identified on radiographs, MR images and scintigraphy in a patient with right ankle pain. The absence of episodes of acute trauma, and the presence of acute clinical manifestations should guide the clinical suspicion.

Abstract: Calcific tendinosis (tendonosis/tendonitis) is a condition which results from the deposition of calcium hydroxyapatite crystals in any tendon of the body. Calcific tendonitis usually presents with pain, which can be exacerbated by prolonged use of the affected tendon. We report a case of calcific tendinosis in the posterior tibialis tendon at the navicular insertion. The pathology is rare in the foot, and extremely rare in the tibialis posterior tendon, indeed there are only 2 reported in the published literature. This case report highlights the need to consider calcific tendinosis in the foot despite its rarity. If this diagnosis is considered early, appropriate investigations can then be requested and unnecessary biopsies, use of antibiotics and surgery can be avoided. We also discuss possible causes of calcific tendinosis in the tibialis posterior tendon, the role of imaging modalities and review treatment methods.

T2 and apparent diffusion coefficient (ADC) values of cartilage were measured after being processed at the workstation, and the differences were statistically analyzed between the two groups. Results: The mean T2 and ADC values of cartilage in early injury group and health group were respectively 51.58+-4.15 ms and 1.78+-0.35 x10-3mm2/s, 39.54+-4.02 ms and 1.44+-0.17 x10-3 mm2/s. There was significant difference between the values of T2 and ADC. Conclusion: T2 and ADC values in early cartilage injury have obviously increased. T2-mapping and DWI have high clinical value in the diagnosis of early articular cartilage injury.

Abstract: Metallosis and metal-induced synovitis are well-recognized complications of metal-backed polyethylene joint prostheses and have been frequently described in the orthopedic surgery literature; however, relatively fewer articles discussing the radiologic aspects of this complication have been published. To illustrate the importance of radiologic findings in the diagnosis and management of these patients, we present a case of metallosis and metal-induced synovitis complicating two revisions of a total knee arthroplasty, caused by polyethylene liner wear and dissociation of the polyethylene liner from the metal-backed patellar prosthesis. Specific attention is given to reviewing signs that aid in diagnosis, such as the "bubble sign," "cloud sign," and "metal-line signs."

Abstract: A 31 years old female presented with swelling and pain above the right knee for three years. On examination, there was a tender swelling over the right knee more pronounced over the suprapatellar region. Plain X-ray, US, CT scan and MRI of the knee were suggestive of Primary synovial osteochondromatosis (PSC) of the suprapatellar pouch. Patient underwent total synovectomy and the diagnosis of synovial osteochondromatosis was confirmed histopathologically. Recognizing the imaging appearances of PSC is important to improve patient management.

Abstract: Gout is usually thought of as a peripheral joint disease. However, case reports are available describing gouty lesions in the spine. We report a case of a 51 year old African American woman with no previous history of gout who presented with lower back pain and fever and was found to have multiple small fluid collections in the paraspinal muscles at the L3 to L5 levels on the MRI. She was empirically treated with antibiotics, since the fluid was not accessible for drainage initially. Unsuccessful antibiotic therapy and an episode of peripheral gout during this hospitalization prompted the diagnosis of axial gout as the cause for the paraspinal lesions in this patient. CT guided aspiration of the paraspinal lesions confirmed monosodium urate (gout) crystals under polarized microscopy.

Abstract: Gout is a systemic, metabolic disease that typically affects the peripheral joints. We describe an unusual presentation of gout affecting the facet joints and costovertebral joints in the thoracic and lumbar spine. A 54-year old man presents to the emergency department with increasing swelling and pain at the left elbow for one week and difficulty ambulating. The imaging work-up included plain radiographs of the left elbow, left wrist, and chest with subsequent admission for possible septic arthritis. MRI of the elbow showed olecranon bursitis and an erosion of the lateral epicondyle. CT scan demonstrated lytic cloud-like lesions localized to the facet joints and costovertebral joints of the thoracic and lumbar spine as well as bilateral medullary nephrocalcinosis. Possible hyperparathyroidism manifestations (including Brown tumors and medullary nephrocalcinosis) were evaluated with plains films of the hands; x-rays instead showed classic gouty arthritis. Our report reviews the disease, epidemiology, classic radiologic findings, and treatment of gout.

Abstract: The authors present an unusual case of atypical iliopsoas bursitis in an 81 years-old female patient. The patient asked for medical advice due to a chronic left hip and lower abdominal pain with no specific characteristics. Physical examination revealed a palpable left-sided pelvic mass. Ultrasound examination demonstrated a purely cystic mass that was presumed to be an ovarian cystic malignancy. The patient was referred for an MRI examination, which showed a cystic lesion extending from the left iliac crest to the anterior aspect of the ipsilateral hip joint (maximum diameter 18 cm), coursing below the iliopsoas tendon indicative of an extremely distended iliopsoas bursa.

Abstract: Osteopoikilosis presents as round or ovoid sclerotic lesions with an appearance like enostosis on pathology. Synovial osteochondromatosis occurs due to cartilaginous metaplasia with synovial villous proliferation with calcified nodules in proximity to joints. A case of osteopoikilosis associated with synovial osteochondromatosis is described. Intraosseus and juxta osseus sclerotic bone lesions were identified on radiographs and computed tomography in a patient with knee pain. The association of osteopoikilosis with synovial osteochondromatosis is rare and to our knowledge has received little attention in the literature.

Abstract: Third generation cementing technique is now commonly used for total hip arthroplasty. The aim of this technique is to sufficiently pressurise the cement and allow maximal penetration of the cement into any remaining trabecular bone to provide a stable fixation of the prosthesis. We report a case where this pressurisation resulted in polymethylmethacrylate retrograde filling of the nutrient vessel and we discuss the controversial diagnosis and current literature surrounding this rare phenomenon.

Abstract: Tuberculosis (TB) of the scapula is an unusual presentation of musculoskeletal tuberculosis. In an endemic area, this rare presentation may become more frequent. The indolent nature of tuberculous bone and joint disease often leads to delayed or missed diagnosis. It is not uncommon for this disease to mimic malignancy. Therefore, the prompt recognition of distinguishing features is vital for correct diagnosis. In particular, imaging is a key tool in helping to make the diagnosis, through the recognition of certain key radiological patterns. However, as there are no pathognomonic imaging findings, the diagnosis rests on histopathological and microbiological confirmation. We report a case of tuberculous osteomyelitis of the scapula. This entity has not received much attention in literature. Pure tuberculous osteomyelitis involving flat membranous bone, as depicted in this report, is rare. Our patient also had an ovarian malignancy, which had decreased our index of suspicion. We therefore present this case as tuberculosis masquerading a cystic scapular metastases.

Abstract: Heterotopic ossification refers to formation of lamellar bone in soft tissues. The etiology is diverse and includes genetic, post-traumatic, and metabolic causes. Elicitation of bone morphogenic proteins are thought to play a key role in the pathogenic process. Initially, heterotopic ossification presents a clinical and radiographic challenge in that it can be mistaken for other more worrisome entities which present with calcified soft tissue masses. However, a spontaneous clinical resolution, temporal relationship to an inciting agent, and radiographic evolution to a peripherally-calcified lesion are all clues to the diagnosis. Here we present the clinical and radiographic features of heterotopic ossification as a result of an infiltrated peripheral IV.
