Abstract
|
|
|
|
Leiomyosarcomas of the large veins are uncommon tumors commonly originating from the inferior vena cava. A primary leiomyosarcoma arising from the renal vein is very uncommon. Herein, we describe the detailed multidetector computed tomography and magnetic resonance imaging findings of a renal vein leiomyosarcoma with both extraluminal and intraluminal components in a 55-year-old woman. The intraluminal component in the renal vein, a heterogeneous enhancement caused by combined necrosis and portions of low or intermediate signal on T2-weighted images are imaging findings that suggest the diagnosis of primary leiomyosarcoma of the renal vein.
