Renal angiomyolipoma: A radiopathological diagnosis

Angiomyolipoma (AML) is a benign renal neoplasm derived from perivascular epithelioid cells and composed of fat, and vascular and smooth muscle element besides spindle cells. It has an incidence of 0.3 - 3% and has increased due to advances in imaging modalities. The overall female to male ratio is approximately 4:1 which is suggesting hormonal component to tumor growth. It can occur sporadically or may be associated with tuberous sclerosis complex. We present a case of renal angiomyolipoma in a 28 year old woman who presented with symptoms of pain off and on and the diagnosis was based on the computed tomography and was confirmed on histopathology.
