Angiographic investigation of 3 cases of secondary renal tumors disclosed each to be vascular, the lung metastasis especially so. Two cases (embryonal cell and bronchogenic carcinomas) exhibited arterial tumor encasement and renal vein obstruction. Demonstration of tumor vessels within the metastasis from the synovial sarcoma was enhanced following intra-arterial epinephrine. These observations broaden the spectrum of angiographic findings previously encountered with secondary renal tumors.
