Angiomyolipoma of the liver.

The radiological features of a case of angiomyolipoma of the liver are reported. A review of the literature has shown this to be a rare benign tumour. The lesion falls within the broad spectrum of lipomatous liver tumours. The angiomyolipoma was shown to be a well defined, fat-density mass on computed tomography. The mass was echogenic, with a sharp margin, on ultrasound. Angiography showed the lesion to be vascular. The preoperative diagnosis of a lipomatous tumour was therefore possible.
