XXXX : diagnostic features on cross-sectional imaging.

@entity1 @entity5 @entity4 @entity1350 @entity11293 @entity490 @entity3 @entity6323
AIM: To evaluate the cross-sectional radiological appearances and to review the clinical presentation and outcome of @entity1 with @entity6323 (IVC @entity11293 ). These are rare aggressive @entity5 that present late with non-specific symptoms and have a poor prognosis. MATERIALS AND METHODS: From January 2002 to December 2008, the radiological images of 23 sequential @entity1 with pathologically proven IVC @entity11293 were independently reviewed by two experienced radiologists. The clinical presentation, treatment including surgical details, and outcome were recorded. RESULTS: There were 19 females and four males with a mean age of 53 years. CT typically demonstrated a large, lobulate, non-calcified heterogeneous mass with peripheral enhancement. T1-weighted magnetic resonance imaging (MRI) images demonstrated a mass with a low signal intensity and T2-weighted MRI images demonstrated a mass with a high signal intensity. Clinical presentation included leg @entity4 , back and @entity490 with almost 50% of @entity1 presenting with @entity3 . Eleven @entity1 underwent ablative surgery. The mean survival time of all @entity1 in the study was 34 months and that of the 11 post-surgical @entity1 was 56 months. CONCLUSION: There are a variety of diagnostic features on both computed tomography (CT) and MRI which aid the diagnosis of this @entity1350 . CT is vital in determining the location of the @entity5 within the IVC and MRI accurately depicts its extent and the potential for surgical resectability, which offers the only chance of survival.
