[Angiomyolipomas of the liver. Diagnostic and therapeutic aspects in 4 cases and review of the literature].

In four cases, angiomyolipoma of the liver was discovered incidentally by ultrasound investigation. Based on a review of 26 other previously reported cases and as was borne out in our series, the diagnosis is suggested by the demonstration of fatty material on CT-scan and confirmed by needle aspiration biopsy. Magnetic resonance may be contributive as well.
