Abstract

Twenty-five patients with renal carcinoma where the tumor had invaded the vascular structures were studied with MR, using superconductive apparatus. In 15 a simple compression and/or dislocation was demonstrated, while in 10 cases the presence of neoplastic thrombosis was found, involving the left renal vein alone in one case, the infrahepatic cava in 4 cases, the intrahepatic cava in 3 cases and suprahepatic cava in two cases. In all cases MR correctly demonstrated the presence and extent of the thrombosis; one patient was judged inoperable because of infiltration of the suprahepatic caval wall. With spin-echo (SE) technique we had only one false negative case; with SE sequences MR had an accurancy of 96%, specificity of 100% and sensibility of 90%. With gradient.echo (GE) technique, accuracy, specificity and sensibility were 100%. So MR, with SE and GE techniques, can be considered as very effective for the study of vascular involvement in patients with kidney tumors, with the aim of obtaining a correct pre-operative balance.
