Inadvertent intravesicular placement of a vaginal contraceptive ring: a case report and review of literature by Kevin S Baker et al.

Free full text article: Inadvertent intravesicular placement of a  vaginal contraceptive ring:  a case report and review of literature

Fulltext article    PDF fulltext

Abstract: The NuvaRing® is a deformable, ring-shaped hormonal contraceptive device which is typically vaginally self-inserted by the patient. While there are several potential side effects of usage, essentially all of them result from hormone delivery. Complications from incorrect placement are rare. We present the case of a 31 year old female who presented to our emergency department after being unable to retrieve a NuvaRing® for its scheduled removal. CT scan showed a hypodense intravesicular NuvaRing® which the patient had inadvertently placed transurethrally 3 weeks prior. Cystoscopy was performed and retrieval using a 3-pronged grasper was eventually successful after several failed attempts with an alligator grasper. Our purpose in presenting this case is to introduce the reader to a rare complication of incorrect NuvaRing® placement, explain how this complication may occur as a result of NuvaRing® construction/functionality, describe how alternative cystoscopic instruments may aid in cystoscopic retrieval, and review the 3 other case reports of intravesicular NuvaRing® placement to discuss the utility of various imaging modalities when clinical suspicion of the complication is high.

Lumbar discal cyst: Diagnostic discography followed by therapeutic computed tomography-guided aspiration and injection by Yoshimi Endo et al.

Published: 2014 Dec
Issue: 8(12) :: Pages: 35-40


Free full text article: Lumbar discal cyst: Diagnostic discography followed by therapeutic computed tomography-guided aspiration and injection

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.

Pentalogy of Cantrell with Ectopia Cordis: CT Findings by Ali Pirasteh et al.

Published: 2014 Dec
Issue: 8(12) :: Pages: 29-34


Free full text article: Pentalogy of Cantrell with Ectopia Cordis:  CT Findings

Fulltext article    PDF fulltext

Abstract: A 14-month-old girl with pentalogy of Cantrell, a very rare congenital syndrome characterized by an epigastric omphalocele and malformations of the heart, sternum, pericardium, and diaphragm, underwent echocardiography and multidetector computed tomography before surgical repair of these deformities was attempted. These tests revealed multiple cardiovascular and noncardiovascular abnormalities. After surgery, the patient`s cardiovascular status was stable. Although studies have shown that echocardiography, multidetector computed tomography, and magnetic resonance imaging may each play a role in the diagnosis and management of this condition, there are few data available to support the use of one imaging modality over another.

Ischemic Colitis Due to a Mesenteric Arteriovenous Malformation in a Patient with a Connective Tissue Disorder by Peter D. Poullos et al.

Published: 2014 Dec
Issue: 8(12) :: Pages: 9-21


Free full text article: Ischemic Colitis Due to a  Mesenteric Arteriovenous Malformation in a Patient with a Connective Tissue Disorder

Fulltext article    PDF fulltext

Abstract: Ischemic colitis is a rare, life-threatening, consequence of mesenteric arteriovenous malformations. Ischemia ensues from a steal phenomenon through shunting, and may be compounded by the resulting portal hypertension. Computed tomographic angiography is the most common first-line test because it is quick, non-invasive, and allows for accurate anatomic characterization. Also, high-resolution three-dimensional images can be created for treatment planning. Magnetic resonance angiography is similarly sensitive for vascular mapping. Conventional angiography remains the gold standard for diagnosis and also allows for therapeutic endovascular embolization. Our patient underwent testing using all three of these modalities. We present the first reported case of this entity in a patient with a vascular connective tissue disorder.

Solitary Fibrous Tumor of the Infratemporal Fossa by Monika E. Freiser et al.

Published: 2014 Dec
Issue: 8(12) :: Pages: 1-8


Free full text article: Solitary Fibrous Tumor of the Infratemporal Fossa

Fulltext article    PDF fulltext

Abstract: Solitary fibrous tumors represent fewer than 2% of all soft tissue tumors, and only about 12-15% of them occur in the head and neck. We report a case of a 38-year-old male who presented with a six-month history of increasing right cheek swelling. Computed tomography of the paranasal sinuses with contrast demonstrated a well-circumscribed avidly enhancing mass in the right retroantral fat. On magnetic resonance imaging the lesion was homogenously slightly hyperintense to muscle on T1 weighted and T2 weighted images and enhanced avidly with contrast. Surgical resection was performed and pathology was consistent with solitary fibrous tumor. There have been very few reported cases of solitary fibrous tumors in the infratemporal fossa and none described as originating in the retroantral fat.
