Simultaneous sonographic demonstration of tumor thrombus in the inferior vena cava and patient main renal vein in renal carcinoma.
With the introduction of new imaging modalities the optimal protocol for the evaluation of renal tumors is under close review. Angiographers frequently are faced with the question of whether to proceed to inferior venacavography following a selective renal angiogram that demonstrates a patent renal vein. We report a case of renal cell carcinoma in which the main renal vein was shown by ultrasound to be unequivocally patent but at the same time there was considerable tumor extension into the inferior vena cava. The necessity of full examination of the inferior vena cava, either by venacavography or ultrasound, in all cases of renal cell carcinoma is stressed.
