Multiple hepatic angiolipomas: a case report and review of literature

Follow-up of two hepatic angiolipomas in a patient without evidence of tube rous sclerosis is reported. Initially, the lesions presented as homogenousl y enhancing masses, which were nearly isodense to normal liver tissue on pl ain CT scans. Focal nodular hyperplasia was assumed. One year later, fat wa s detected in the growing tumors and percutaneous core biopsy reveled hepat ic angiolipomas. Natural history of these rare lesions is unknown, and this is to the best of our knowledge the first observation of fatty metamorphos is in such a benign, mesenchymal hepatic neoplasm.
