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.

Spinal angiolipoma is a rare, benign tumour. More than 90% of cases arise extradurally. The authors report an extradural spinal angiolipoma in a 54-year-old man. Conventional T1-weighted and T2-weighted magnetic resonance imaging (MRI) demonstrated an excessive amount of extradural adipose tissue posteriorly, extending from the level of the third to the ninth thoracic vertebra. The signal intensity within the spinal cord was normal. These findings were initially misinterpreted as being of little clinical significance. When the patient's condition deteriorated, myelography was performed, and extradural compression of the thecal sac was demonstrated. At surgery spinal angiolipoma was confirmed. The ease with which the MRI features of this lesion can be overlooked, as well as imaging strategies to avoid this pitfall, are discussed.
