Renal adenocarcinoma in adolescence and childhood: emphasis on angiographic findings

Four cases of hypernephroma occurring in the first 2 decades of life are presented. Of these patients 3 were adolescents and 1 was a child. Angiography was used in 8 cases, including 6 that were reported previously and 2 from the present series. Sparse neovascularity, faint tumor stain and no arteriovenous shunting were the manifestations in 4 cases. Differentiation from Wilms tumor could be difficult in this circumstance.
