Angiography in leiomyosarcoma of the inferior vena cava--report of two cases.

Two patients with leiomyosarcoma of the suprarenal inferior vena cava are presented. In one case the tumour was misinterpreted as intrahepatic at angiography. In the second case an extrahepatic location was suggested after repeated angiography. The diagnosis should be borne in mind when a large hypovascular mass appears to be located centrally in the liver at coeliac angiography and when ultrasound examination has revealed its solid nature.
