“…Lipomatous lesions may be determined as hyperintensity on in-phase image and a relative decrease of signal intensity on out-of-phase image. 20 , 21 In this study, numerous lipid components were found in the tumors of 4 cases of mixed subtype HAML using magnetic resonance chemical shift imaging technique. However, these findings should be clarified in patients with HCC associated with steatosis.…”

Hepatic angiomyolipoma (HAML) is a rare mesenchymal tumor of the liver with marked histological diversity. The present study was to review the magnetic resonance imaging (MRI) and clinical pathological features of HAML resembling hepatocellular carcinoma (HCC).Nine patients who underwent surgical resection and had pathological diagnosis of HAML were retrospectively analyzed.All of 9 patients (5 males and 4 females) had a solitary hepatic mass with a median size of 4 cm (from 1.4 cm to 15.3 cm). Seven cases were identified as incidental liver tumors during health screening and 2 patients were diagnosed for hepatic mass when visited hospitals with unspecific abdominal discomfort. Before resection, 6 cases were diagnosed as HCC on MRI. MRI on chemical shift imagings showed a large amount of lipids in 5 cases. The enhancement pattern of MRI was classified into 2 types: in 2 cases, lesions with small or no vessels that demonstrated prolonged enhancement (1 mixed subtype and 1 myomatous subtype) and in 7 cases, lesions with abundant central vessels that show rapid washout (3 mixed subtypes and 4 myomatous subtypes) in the portal venous/delayed phase. All patients underwent resection of hepatic tumor and no recurrence was observed during follow-up (range: 2–24 months) of median 10 months. By immunohistochemistry, the tumor cells demonstrated positive immunostaining for human melanoma black-45, smooth muscle actin, and CD34.In conclusion, all of 9 patients with HAML presented with none or nonspecific clinical manifestations. The diagnosis of HAML relies on disease and immunohistochemistry, but not MRI due to its resemblance to HCC.

The purpose of our study was to describe contrast-enhanced magnetic resonance angiography (MRA) findings of hepatic angiomyolipoma (AML) with less lipocyte. We reviewed the MRA findings of five resected lesions of hepatic AML with less lipocyte specimens and found that the efferent vessels of hepatic AMLs were the hepatic veins. These findings corresponded well with those seen on conventional contrast-enhanced dynamic CT scans. This hemodynamic finding may be an important characterization of hepatic AML with less lipocyte, and could distinguish AML from other benign and malignant hepatic tumors.
