Multifocal angiomyolipoma in a patient with tuberous sclerosis.

Angiomyolipomas are rare lesions that occur most commonly in the kidney, but also can occur in the liver and rarely, in the lymph nodes. Its rare association with tuberous sclerosis has been suggested, but never proved. We report a patient with multiple visceral angiomyolipomas as well as visceral vessel aneurysms and tuberous sclerosis. The association of the three lesions suggests a possible common connective-tissue defect.
