Abstract

Renal angiomyolipoma is an uncommon hamartial and benign tumor. There are two types of renal angiomyolipoma. One is associated with tuberous sclerosis, which is small, bilateral and usually not combined with symptom. The other is not associated with tuberous sclerosis, which is large, solitary and usually combined with symptoms. But bilateral renal angiomyolipomas without the stigma of tuberous sclerosis have been reported rarely. In most of them bilateral lesions were found at same time. We present a case of 32 years old woman with bilateral. renal angiomyolipomas without tuberous sclerosis. This patient was undergone right nephrectomy due to angiomyolipoma on November, 1981 and left kidney was normal at that time. 3 years after operation, patient was diagnosed as left renal angiomyolipoma by CT scanning.
