Angiomyolipomas (AMLs) of kidneys are one of the common extracranial manifestations of tuberous sclerosis (TSC). AMLs when large may cause life-threatening hemorrhage, but seldom undergo malignant degeneration. We describe the appearance of renal AML degenerated to angiosarcoma on (18)F-flruorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and contrast-enhanced CT (CECT).
