PATHOLOGIC VASCULARITY OF RENAL ANGIOMYOLIPOMA - CAST CORROSION AND ANGIOGRAPHIC STUDY

Angiomyolipomas of the kidney at times have been preoperatively identified by the interlobar or interlobular artery aneurysms in the early vascular phase of renal arteriograms. A case report is presented in which a plastic cast corrosion technique was used postnephrectomy to demonstrate the presence of aneurysms identified angiographically prior to surgery. Portions of a cast corrosion model of a hypernephroma are also exhibited to compare and contrast pathologic vascular features of both types of tumors. © 1979.
