Exophytic well defined hyperechoic mass lesion seen in the lower pole of the left kidney with no internal calcification or detectable vascularity. The lesion demonstrates posterior acoustic enhancement.
Case Discussion
Renal angiomyolipoma is the most common benign solid renal lesion with a female predilection. It is sporadic in most cases however it could be associated with phakomatoses. Calcification raises the possibility of fat-containing RCC.
