Quiz of the MonthAnswer to Question 1The correct diagnosis is renal angiomyolipoma, a be nign hamartomatous tumor of the kidney.This tumor is rare in the general population but may occur with up to 80% frequency in patients with tuberous sclerosis, a dis ease characterized by epilepsy and mental retardation associated with nodular lesions in the brain and the facial lesions of adenoma sebaceum.Pathologically, this tumor is composed of vascular, fatty, and smoth muscle and may be misdiagnosed as a liposarcoma.Although angio myolipoma is frequently multicentric, this tumor is con sidered a benign process as neither malignant change nor métastasés have been demonstrated.Radiologic features of this tumor are marked radiolucency on plain films due to high lipid content and multiple small arterial aneu rysms without arteriovenous shunting on angiography.However, as in our patient, diagnostic radiologic features may be absent giving an appearance similar to renal cell carcinoma.
