抄録
Hepatic angiomyolipoma (AML) is an uncommon benign mesenchymal tumor of the liver. Most AMLs of the liver are asymptomatic and are discovered incidentally, but the diagnosis remains difficult. We report a case of a 33-year-old woman who had an abdominal mass and in whom diagnosis remained unidentified after imaging and needle biopsy. On dynamic CT, a heterogeneous enhanced hepatic lesion was revealed in the arterial phase with washout in the portal phase. On MRI, it was shown as a hypointense tumor on T1 weighted images and hyperintense on T2 weighted images. Because hepatocellular carcinoma was suspected as a result of the needle biopsy, hepatic segmentectomy was performed. The final pathological diagnosis was AML due to positive HMB45. AML needs to be considered as a condition that may display the atypical images consistent with liver tumor. In cases such as this, we should request the examination of immunohistochemical staining especially for HMB45 on biopsy specimens.
