A patient with angiomyelolipoma of the liver, together with radiological evidence of pancreatic, renal and bony lesions characteristic of tuberous sclerosis, is described. Although the patient had no other clinical features of tuberous sclerosis, her daughter was found to suffer from the classical triad of this syndrome and also has had hepatic lipomatous lesions and bony involvement. This is the first histologically proven case of hepatic angiomyelolipoma associated with tuberous sclerosis.
