title: Leiomyosarcoma of the renal vein: arterial encasement on contrast-enhanced dynamic computed tomography.
abstract: We report a case of leiomyosarcoma of the renal vein, which is a rare tumor with no more than 30 cases found in the published English language literature. This case demonstrates encasement of the renal artery by the tumor mass, a previously unreported manifestation. The present study could be useful in considering this rare tumor in the differential diagnosis of renal hilar tumors.
