- Unusual Concentration of Tc-99m methylendiphosphonate in Rhabdomyosarcoma. [Journal Article]
- J Radiol Case Rep 2012 Sep; 6(9):29-34.
Extraosseous accumulation of bone-seeking agents is rare, but has been previously reported in pediatric sarcomas and neuroblastomas. We present an unusual case of a 5-month-old male with an abdominal mass observed clinically by his parents and referring pediatrician. Contrast abdominal computerized tomography confirmed the presence of a large pelvic mass that was diagnosed pathologically as embryonal rhabdomyosarcoma. A bone scintigraphy that was performed for staging of the disease revealed accumulation of the radiopharmaceutical in the tumor. There was no evidence for skeletal metastatic disease. This case further demonstrates the nonspecificity of soft-tissue tumor uptake on bone scintigraphy.
- One not to miss: ovarian vein thrombosis causing pulmonary embolism with literature review. [Journal Article]
- J Radiol Case Rep 2012 Sep; 6(9):23-8.
Ovarian vein thrombosis (OVT) is an uncommon entity typically seen in the post-partum, patients with pelvic surgery, infection, or inflammation, and hypercoagulabilty. Concurrent pulmonary embolism (PE) may occur in these patients; however, is an uncommon complication. Treatment commonly involves anti-coagulation and antibiotics in the setting of pelvic inflammatory disease. Presented is a case report of ovarian vein thrombosis leading to pulmonary embolism in the setting of malignancy, underscoring the importance of inspecting the gonadal vein during interpretation, particularly in the emergency setting.
- Venous intravasation: a potential pitfall of confirmatory hysterosalpingogram following essure hysteroscopic sterilization. [Journal Article]
- J Radiol Case Rep 2012 Sep; 6(9):18-22.
Indications for hysterosalpingography (HSG) include evaluation of infertility, spontaneous abortions, postoperative evaluation of tubal ligation, pre-myomectomy evaluation, and more recently, evaluation of tubal occlusion after placement of the Essure Permanent Birth Control System. Here we report a case of venous intravasation during a routine post-Essure HSG, a phenomenon in which contrast transits from the uterine cavity, through the myometrium, and directly into draining pelvic veins. Venous intravasation is a potential pitfall in interpretation of HSGs.
- Calyceal diverticulum - a mimic of different pathologies on multiple imaging modalities. [Journal Article]
- J Radiol Case Rep 2012 Sep; 6(9):10-7.
Calyceal diverticula are outpouchings of a renal calyx. Often found incidentally on radiological imaging, they are generally benign and usually asymptomatic, although complications include infection and stone formation. More importantly, calyceal diverticula may mimic other potentially more serious pathology on imaging, such as renal tumour or abscess on ultrasound or computed tomography and even rib metastasis on bone scintigraphy. We present a case of a patient with a calyceal diverticulum found incidentally on imaging, in which the diverticulum is demonstrated on ultrasound, computed tomography, intravenous urogram and bone scintigraphy, and discuss the potential differential diagnoses that need to be excluded in this condition.
- Supine digital subtraction myelography for the demonstration of a dorsal cerebrospinal fluid leak in a patient with spontaneous intracranial hypotension: a technical note. [Journal Article]
- J Radiol Case Rep 2012 Sep; 6(9):1-9.
A patient with spontaneous intracranial hypotension due to a spinal cerebrospinal fluid (CSF) leak required localization of the leakage site prior to surgical management. Conventional, computed tomography and prone digital subtraction myelography failed to localize the dural tear, which was postulated to be dorsally located. We present here a digital subtraction myelographic approach to accurately localize a dorsal site of CSF leakage by injecting iodinated contrast via a lumbar drain with the patient in the supine position.
- Seahorse. [Journal Article]
- J Radiol Case Rep 2012 Jun; 6(6):35-6.
- Percutaneous embolization of an incidentally diagnosed pulmonary aneurysm in a scleroderma patient. [Journal Article]
- J Radiol Case Rep 2012 Jun; 6(6):29-34.
A 59-year-old female with history of progressive scleroderma and pulmonary fibrosis was referred for biopsy of a pulmonary nodule that was discovered on computed-tomography (CT) chest surveillance, not present on prior CT- scan. Imaging was suspicious for granuloma, malignancy or aneurysm. CT- Angiography (CTA), performed immediately before the procedure, did not show enhancement of the mass, followed by placement of coaxial-needle into the mass. Suspicion of aneurysm was again raised and repeat CTA demonstrated contrast filling of the aneurysm. With the coaxial-needle in the aneurysm, embolization of the sac was performed using microfibrillar collagen, followed by confirmation of containment and thrombosis with CT.
- Colonic angiolipoma - a rare finding in the gastrointestinal tract. Case report and review of literature. [Journal Article]
- J Radiol Case Rep 2012 Jun; 6(6):23-8.
Angiolipomas are benign lesions that are frequently found in subcutaneous cellular tissue, but are rarely located in the gastrointestinal tract. Here we discuss a case of colonic angiolipoma that presented as a mass near the hepatic flexure, occupying approximately 90% of the colonic lumen. The diagnosis was made by endoscopy and computed tomography. The mass was resected successfully and diagnosis was confirmed by histological studies and immunohistochemical tests.
- Hydrocele of the canal of Nuck: value of radiological diagnosis. [Journal Article]
- J Radiol Case Rep 2012 Jun; 6(6):18-22.
Hydrocele of the canal of Nuck (cyst of the canal of Nuck) is the female homologue of hydrocele of the spermatic cord in males and is a rarely encountered entity, mostly diagnosed on the operating table at the time of suspected inguinal hernia surgery, as the clinical presentation usually is subtle and inconclusive. Diagnosis is mainly by ultrasound and has shown varied presentation of the same over the years. We discuss the sonographic findings of a case of hydrocele of the canal of Nuck.
- Subscapular tumoral calcinosis in a toddler: case report. [Journal Article]
- J Radiol Case Rep 2012 Jun; 6(6):10-7.
Tumoral calcinosis is uncommon in toddlers, and rare within the subscapular area. Although typically benign, tumoral calcinosis is often incorrectly diagnosed prior to biopsy. We present a case of subscapular tumoral calcinosis in a 16-month old girl and discuss the radiological findings on X-ray, ultrasound, computed tomography and magnetic resonance imaging, including the first description of T1-weighted post contrast imaging, which demonstrate the fibrotic components of tumoral calcinosis.
