Angiomyolipomas (AMLs) are one group of benign tumours that are distinguishable radiologically. Because AMLs are composed of different tissues which include fat, muscle, vascular elements, and even cartilage, the fat in particular, may be detected radiologically. Angiomyolipomas, particularly when they are small, warrant no treatment. They are resected only when they are over 4 cm or when they are symptomatic due to the risk of bleeding.
