[Renal angiomyolipoma]

Abstract

Renal angiomyolipoma is a benign tumor that can be observed in two distinct types: the solitary type and the tuberous sclerosis associated type. It is now diagnosed, even if asymptomatic, with increasing frequency by means of ultrasonography and computerized tomography owing to its particular features. The possibility of preoperative diagnosis and the biological characteristics of this benign lesion should induce a more conservative management.
