Hepatic angiomyolipoma is a rare liver pathology. In this case report, we describe MRI features of a hepatic angiomyolipoma with a high fat content, which was indeterminate on CT. In phase and out of phase T1-weighted spoiled gradient echo technique, T2-weighted fat suppressed fast spin echo technique and dynamic enhanced T1-weighted in phase gradient echo technique were used. Out of phase gradient echo sequence was the most sensitive technique identifying the fat content of the lesion in its mixed tissue composition.
肝血管平滑肌脂肪瘤是一种罕见的肝脏病变。在本病例报告中，我们描述了一例高脂肪含量的肝血管平滑肌脂肪瘤的MRI特征，其在CT上表现不明确。采用了同相位和反相位T1加权扰相梯度回波技术、T2加权脂肪抑制快速自旋回波技术以及动态增强T1加权同相位梯度回波技术。反相位梯度回波序列是在病变混合组织成分中识别脂肪含量最敏感的技术。
