Abstract
Leiomyosarcoma of the inferior vena cava is a rare disease with protean manifestations related to the location of the tumor. Urological manifestations of the disease are rare and include renal vein thrombosis and renovascular hypertension. Approximately 63 cases have been reported in the literature, with a striking female predominance. Presentation as an isolated suprarenal mass has not been reported previously. We discuss this unusual tumor and report a case that presented as an asymptomatic suprarenal mass.
