title: CT diagnosis of tumor thrombosis of the renal vein and inferior vena cava.
abstract: Four cases of tumor thrombosis of the inferior vena cava and renal veins were diagnosed by computed tomography. In two, the thrombus itself was demonstrated within the vascular lumen after intravenous injection of urographic contrast material. The diagnosis was made in the other two patients by identification of massive enlargement of the vascular diameter.
