ObjectiveTo study the clinical feature, diagnosis, treatment and prognosis of hepatic angiomyolipoma.Methods The clinical materials of eight surgically treated patients with hepatic AML were retrospectively analyzed.ResultsThere were five females and three males, with age ranging from 25 to 59 years (mean 39 6 years). Tumors were located in the right lobe of the liver in 5 cases, and in the left lobe in 3 cases. Ultrasonography and computed tomography were performed in all cases. Magnetic resonance imaging and angiography were done in two each cases. The myoid cells in all tumors showed over expression of HMB 45. One patient died of postoperative heart failure, seven were followed up for 9 mos to 12 years without tumor recurrence. Conclusions Comprehensive imaging features can reveal the characteristic components of hepatic angiomyolipoma. HMB 45 immunostaining can be used to confirm the diagnosis. Surgical resection is an effective treatment of hepatic AML.
