Angiomyolipoma AML is a relatively uncommon tumor that can be associated with renal lesions in connection with sporadic or associated tuberous sclerosis disease. These lesions are often found incidentally and managed conservatively with periodic imaging and clinical surveillance, depending on the actual size of the lesion. Lesions greater or equal to 4 cm have been found to have an increased risk for retroperitoneal hemorrhage and may be managed more aggressively. CT scan is currently the imaging modality of choice and the presence of fat within a renal mass is highly suggestive of AML. Other imaging modalities such as ultrasound and MR are also utilized in the evaluation of these renal masses if CT is contraindicated.
