It is suggested that no follow-up is needed for Angiomyolipoma-like incidental imaging findings measuring less than 1 or 2 cm. Alternatively, a renal ultrasonography every 3 or 4 years has been suggested for angiomyolipoma-like masses measuring less than 2 cm. This topic last updated: Dec 30, 2017. For those measuring 2 to 4 cm, annual ultrasonography is recommended. Those over 4 cm are usually surgically removed, but for those that are not, it is recommended to perform an ultrasonography after 6 months, and then annually if stable.
