Rare mediastinal masses - imaging review.

Mediastinal masses span a wide histopathological and radiological spectrum. Apart from primary thymic/thyroid masses and lymphomas, all other mediastinal masses can be considered rare tumors. Chest radiography and Computed tomography (CT) are helpful to characterize the mass and can reach a diagnosis or a close differential diagnosis.

Primary free fibula reconstruction in life-threatening haemorrhage from high flow arteriovenous malformation of mandible.

Background: High flow arteriovenous malformation (AVM) of the mandible is rare, but it can present as a life-threatening emergency with severe intraoral bleeding for the first time. The gold standard of treatment for an AVM of the mandible is selective embolisation combined with resection and subsequent reconstructions. With the advent of advanced multidisciplinary techniques aimed at definitive therapy, surgical resection and primary reconstruction can provide an ideal anatomical and functional cure.

Imaging features of Ewing's sarcoma: Special reference to uncommon features and rare sites of presentation.

Context: Ewing's sarcoma (EWS) commonly involves long bones with a permeative pattern of bone destruction and aggressive interrupted periosteal new bone formation. However, radiological features show wide variation and some presentations are uncommon, leading to diagnostic confusion. This study is aimed at studying the imaging features of proven EWS and highlight the uncommon features and rare sites of presentation.

Pharmaco Penile Duplex Ultrasonography in the Evaluation of Erectile Dysfunction.

Introduction: The National Institute of Health defined 'erectile dysfunction' as the persistent inability to achieve and/or to maintain an erection for a satisfactory sexual performance. In last few years, the concept of erectile dysfunction has evolved from that of a disorder referred to as 'impotence' which used to be considered predominantly psychogenic to that of 'Erectile Dysfunction' (ED), a well understood physiologic result of multiple risk factors, both psychological and organic. The most common cause of organic erectile dysfunction is vasculogenic causes.

Imaging features of primary tumors of the spine: A pictorial essay.

Primary tumors of spine are rare accounting for less than 5% of new bone tumors diagnosed every year. These tumors may exhibit characteristic imaging features that can help in early diagnosis and improved prognosis. Plasmacytoma/multiple myeloma and lymphoproliferative tumors are the most common malignant primary spinal tumors.

Radiological features of metastatic gastrointestinal stromal tumors.

The imaging features of 42 histopathologically confirmed cases of Gastrointestinal Stromal Tumors (GIST) were analyzed, to observe the pattern of metastasis. At presentation 22 of 42 patients (52.3%) showed metastasis.

Utility of fine needle aspiration cytology in mediastinal lesions: a clinicopathologic study of 1617 cases from a single institution.

Objective: To study the distribution, prevalence and cytomorphologic features of mediastinal lesions and assess the utility of fine needle aspiration cytology (FNAC) in such lesions by correlating with clinical, laboratory and imageologic parameters.

Study Design: A retrospective study was performed of mediastinal lesions that were referred for ultrasonographic/computed tomography-guided FNAC during the years 2001-2006. Correlation was done wherever possible using the following parameters: histology, bone marrow, imageology, tumor markers, cytology, immunohistochemistry, antecedent history and regression after therapy.
