Angiographic manifestations of bilateral Wilms' tumor

Two cases of bilateral Wilms' tumor are presented with discussion of angiographic features. Emphasis is placed on selective angiography in addition to inferior vena cavography for complete evaluation. Because of the incidence of bilateral disease, and the highly vascular nature of the tumor, selective angiography of the contralateral side should be considered in the initial evaluation of unilateral Wilms'tumor. Evaluation of the interface between tumor and normal parenchyma is extremely important in bilateral disease, in anticipation of partial nephrectomy.
