A 63-year-old women was referred for follow up of an angiomyolipoma previously diagnosed on CT scan. Ultrasound during follow up indeed showed a 25 mm large, strong hyperechoic tumor (marked with an asterix) in the upperpole of the left kidney consistent with an angiomyolipoma. The echogenicity corresponds with a composition of fat, also when compared to fat in the renal hilum.
