[Diagnosis and treatment of renal angiomyolipoma]

Abstract

Fourteen cases of angiomyolipoma have been diagnosed and treated at our center since it opened 19 years ago. The diagnostic methods and therapeutic approach have changed since then. Noninvasive imaging techniques like CT and ultrasound have significantly enhanced the accuracy of diagnosis. The mode of presentation, number, size and the differential diagnosis may decide between conservative or surgical management of these tumors. A small tumor mass only requires observation. For larger ones, the treatment of choice is preferably by conservative surgery or highly selective embolization if permitted by the severity of the disease. Surgery is warranted when doubt exists on CT and ultrasonography.
