"Macro" aneurysm in renal angiomyolipoma: two cases, with therapeutic embolization in one patient.

Two young women with renal angiomyolipomas (AML) containing solitary large aneurysms are presented. In both patients AML was complicated by life-threatening hemorrhage. In the first case a parenchymal sparing procedure was undertaken (heminephrectomy). The second case was treated with interventional radiologic techniques with excellent results despite inadvertent rupture of the aneurysm.
