Chondrosarcoma in Childhood: The Radiologic and Clinical Conundrum by Susan M. Mosier et al.

Abstract: Less than 10% of chondrosarcomas occur in children. In addition, as little as 0.5% of low-grade chondrosarcomas arise secondarily from benign chondroid lesions. The presence of focal pain is often used to crudely distinguish a chondrosarcoma (which is usually managed with wide surgical excision), from a benign chondroid lesion (which can be followed by clinical exams and imaging surveillance). Given the difficulty of localizing pain in the pediatric population, initial radiology findings and short-interval follow-up, both imaging and clinical, are critical to accurately differentiate a chondrosarcoma from a benign chondroid lesion. To our knowledge, no case in the literature discusses a chondrosarcoma possibly arising secondarily from an enchondroma in a pediatric patient. We present a clinicopathologic and radiology review of conventional chondrosarcomas. We also attempt to further the understanding of how to manage a chondroid lesion in the pediatric patient with only vague or bilateral complaints of pain.

Abstract: The differential diagnosis for lesions causing neural foraminal widening is vast. The majority are solitary benign peripheral nerve sheath tumours, such as neurofibromas or schwannomas. We present a case of a rare cause of neural foraminal expansion secondary to a posterior thoracic extradural angiolipoma. We describe the presence of chemical shift artefact on post gadolinium T1-weighted imaging as indirect evidence of a fatty component. This potentially important diagnostic sign may raise the suspicion of angiolipoma, especially in an isointense or hypointense dumbbell lesion on T1-weighted imaging, and has not been described previously in this context. Accurate radiological diagnosis of an angiolipoma is important to reduce unexpected haemorrhagic complications from biopsy or resection of the lesion.

Bladder Schwannoma - A Case Presentation by Andrew D. Mosier et al.

Published: 2012 Dec

Free full text article: Bladder Schwannoma - A Case Presentation

Fulltext article    PDF fulltext

Interactive Image Stack

Abstract: Bladder schwannomas are exceedingly rare, benign or malignant, nerve sheath tumors that are most often discovered in patients with a known diagnosis of Neurofibromatosis type 1 (NF1). A few sporadic case reports of bladder schwannoma have been published in urologic, obstetric/gynecologic, and pathologic journals. However, this is the first case report in the radiologic literature where computed tomography imaging and radiology-specific descriptions are discussed. Furthermore, the patient presented in this case is only the fifth published patient without NF1 to be diagnosed with a bladder schwannoma, to the best of our knowledge.

Rare lymphoid malignancies of the breast: report of two cases illustrating potential diagnostic techniques by Orazio Schillaci et al.

Abstract: Two cases of lymphoid malignancy involving the breast are herein presented. Both patients were admitted with a palpable breast mass. Ultrasound demonstrated hypoechoic, ill-defined lesions of the breast in both patients; mammogram also showed spiculated breast densities. Both patients underwent core biopsy, which revealed lymphomatous cells. Total-body evaluation was also performed by computed tomography and positron emission tomography/computed tomography revealing no other fluorodeoxyglucose-avid foci in the first case and supra and subdiaphragmatic disease in the second one.

Dermoid cyst of the pancreas: A case report with literature review by Jason Lane* et al.

Abstract: Pancreatic dermoid cysts represent a rare entity with 35 cases described in the world literature, including the present one. Pre-operative diagnosis is difficult, with definitive diagnosis usually taking place intra-operatively. We report the case of a 63 year old male with a symptomatic, 6 cm cystic mass in the body of the pancreas. The pre-operative evaluation suggested a cystic neoplasm, but was indeterminate as to whether the lesion was benign or malignant. The diagnosis of dermoid cyst was made intra-operatively with frozen section. Although the diagnosis could not be made pre-operatively this retrospective report highlights the difficulty in evaluating cystic pancreatic lesions by imaging and summarizes the current body of knowledge on this rare entity.

A Complex Pulmonary Vein Varix - Diagnosis with ECG gated MDCT, MRI and Invasive Pulmonary Angiography by Zuzana Berecova et al.

Abstract: A case of an asymptomatic 32-year-old male with a complex congenital pulmonary vein varix is reported herein. Chest X-ray incidentally revealed a tubular opacity passing from the periphery of the left lingula to the mediastinum. ECG gated multidetector computed tomography showed the opacity to be a vessel emptying into the left atrium via the left superior pulmonary vein. In addition, a second vascular structure was noted within the posterior mediastinum that was emptying into the same pulmonary vein. These findings were also confirmed by magnetic resonance imaging, 4D magnetic resonance angiography and invasive arterial angiography. Based on multimodality imaging findings the diagnosis of complex congenital pulmonary venous varix with posterior mediastinal extension was established.
