ABSTRACT
Angiomyolipoma is a rare tumor of harmatomatous lesion derived from mesenchyme. The hepatic angiomyolipoma was described by Ishak for the first time in 1976. In this case report, we describe clinical features and treatment with other references. 67-year old female patient referred from private clinic for evaluation of hepatic mass in abdominal sonography and presented dyspepsia during 2 months. CT scan showed 4.8x3.7 cm sized heterogeneous low-density mass (-44 Hounsfield Units) with peripheral rim enhancement at segment 5. MRI showed 4.8x3.7 cm sized well-defined, high signal intensity hepatic mass on both T1WI and T2WI and marked fat suppression on the fat suppression sequence. Prominent tumor was enhanced during arterial phase, subtle remained enhancement on 10 min delayed image on the dynamic study. Intraoperative finding showed well-defined dark brown-colored mass at segment 4b and 5 and no enlarged lymph node, especially #12. We performed segmental resection of 4b and 5 by using Glissonian technique with Helix Hydro-Jet (R) (ERBE Elektromedizin GmbH, Germany). Immunohistochemical staining of specimen was resulted in Vimetin (+), Desmin (-), Actin (+) and HMB-45 (+) and than we diagnosed as hepatic angiomyolipoma. The pateints discharged at 14 days after operation without other problems.
