title: Giant angiomyolipoma with atypical arteriovenous shunting: CT and angiographic studies.
abstract: The advent of both ultrasound and computerized tomography made the pre-operative diagnosis of angiomyolipoma much easier. However, differentiation from retroperitoneal, perinephric space and especially intrarenal liposarcoma remains difficult or impossible. Angiographic findings are atypical and often do not allow differentiation from renal cell carcinoma. Early filling of the renal vein in renal cell carcinoma is sometimes used to distinguish renal cell carcinoma from angiomyolipoma. A case of a giant angiomyolipoma with arteriovenous shunting and early filling of the renal vein is described.
