Parasitic Arterial Supply To Renal Angiomyolipoma

Abstract

A case of a large renal angiomyolipoma in a relatively asymptomatic female subject without tuberous sclerosis is presented. The case demonstrates a parasitized blood supply from a lumbar artery and the superior mesenteric artery, in addition to the characteristic angiographic features that have been reported previously. A parasitized blood supply to renal masses has been considered previously to be associated with malignant processes. It is emphasized that parasitization of a blood supply by a renal mass lesion is not definite evidence of malignancy.

Renal Angiomyolipomas with Inferior Vena cava invasion

“…Most notably, venous invasion, lymph node metastasis, and arterial parasitization have been described. Since 1978, Davis has described a renal AML with a parasitized blood supply from a lumbar artery and the superior mesenteric artery [96]. Hulbert et al reported the involvement of the spleen by renal angiomyolipoma [97].…”
