Epiploic Appendagitis in a Female Patient with Situs Ambiguous Abnormality by Christopher Ryen

Abstract: We report the case of a 23 year-old obese female, with previously diagnosed situs inversus below the diaphragm, who presented with severe left upper quadrant abdominal pain. The patient was believed to have a surgical indication, possibly appendicitis or diverticulitis, and had an emergent abdominal Computed Tomography (CT) scan. The CT was interpreted as epiploic appendagitis with no signs of appendicitis. Epiploic appendagitis is a rare cause of acute abdominal pain, which involves the torsion and eventual necrosis of one of the epiploic appendages. This case was complicated by the fact that the patient had situs inversus below the diaphragm, which made it difficult to relate her localized abdominal pain to the correct anatomic area. The diagnosis allowed the patient to avoid invasive surgery and instead opt for conservative medical management. The utilization of radiologic imaging is of utmost importance in diagnosing this condition, which has characteristic findings on CT, US, and MR, all of which is discussed in this article.

Symptomatic Calvarial Cavernous Hemangioma: Presurgical Confirmation by Scintigraphy by Ajeet Gordhan et al.

Abstract: Hemangiomas are rare tumors in the calvarium and represent 2% of osseous calvarial lesions. Dynamic Tc-99m RBC blood pool scintigraphy has a high positive predictive value for cavernous hemangiomas of the liver. This scintigraphic technique can be used for identifying cavernous hemangiomas at other anatomic sites. We present a case in which a tagged RBC blood pool scan was used for further characterizing a symptomatic calvarial lesion as a cavernous hemangioma. This avoided an unnecessary workup for metastatic disease and was valuable in surgical planning for anticipated increased intra-operative blood loss. Histological confirmation of a cavernous hemangioma was made after surgical resection.

Testicular relapse of non-Hodgkin Lymphoma noted on FDG-PET by Stephen D. Scotti et al.

Free full text article: Testicular relapse of non-Hodgkin Lymphoma noted on FDG-PET

Abstract: Testicular relapse of leukemia and lymphoma is a well-recognized phenomenon, with testicular relapse of lymphoma being more common in the adult population and leukemia relapse being more common in the pediatric population. With the advent of F-18 fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) in the evaluation of lymphoma it is possible to evaluate testicular uptake of FDG and to detect primary testicular lymphoma or testicular relapse on the FDG-PET examination. Testicular relapse of non-Hodgkin lymphoma (NHL) detected on FDG-PET has been reported previously. We report an additional case in which there was testicular activity at presentation, a response to therapy (orchiectomy not performed) and then testicular relapse followed by orchiectomy. We review the literature with regard to testicular recurrence and testicular uptake of FDG-PET. There have been studies that have examined normal standardized uptake value maximum (SUVmax) values in the testicle, with normal values ranging from 2.81 ( 30-39 years) to 2.18 (80-89 years), depending upon age. However, it should be noted that there could be considerable variability in SUVmax values depending upon the units used (e.g. normalized to lean body mass vs. body weight) and depending upon examination variables such as dietary conditions, muscle uptake or extravasation of FDG. Elevated activity or lateralizing activity should be viewed with suspicion, with etiologies including primary testicular tumor, primary or secondary testicular lymphoma and metastatic disease with other etiologies less likely.

Survival to the age of 87 years in a woman with unoperated tetralogy of Fallot by Ty K. Subhawong et al.

Free full text article: Survival to the age of 87 years in a woman with unoperated tetralogy of Fallot

Abstract: Tetralogy of Fallot is the most common cyanotic congenital heart defect, affecting approximately 2700 infants per year born in the United States. The natural history of the tetralogy reflects the adverse physiologic consequences of the underlying structural abnormalities, with only approximately 3% of uncorrected patients surviving past age 40. In this case report, we report an 87-year-old woman with unoperated tetralogy of Fallot, who we believe to be the oldest and only second octogenarian described in the literature.

Extraspinal findings on lumbar spine MR imaging by Nathalie V. Gebara et al.

Published: 2009 Aug
Issue: 3(8) :: Pages: 5-13


Free full text article: Extraspinal findings on lumbar spine MR imaging

Fulltext article    PDF fulltext

Interactive Image Stack

Abstract: Interpretation of radiologic studies requires vigilance on the part of the radiologist to identify findings and abnormalities outside the region of interest. In the case of routine lumbar spine MRI for low back pain, many extraspinal abnormalities can often be identified. Some of these findings may account for low back pain. Other findings are incidental, but may have significant clinical implications, and are important to recognize. We present twenty-four examples of incidental findings from lumbar spine MRI examinations. The findings involve various organ systems, covering a broad range of clinical urgency.

Abstract: We present the clinical, laboratory, computed tomography (CT), single photon emission computed tomography (SPECT), and histopathological findings of a patient with adrenocorticotropic hormone (ACTH) dependent Cushing`s syndrome with massive bilateral adrenal gland hyperplasia due to a hilar ACTH-producing well-differentiated neuroendocrine carcinoma.
