Objective:To investigate the image characteristics of hepatic monotypic epithelioid angiomyolipoma (HMEA) and pathological characters so as to improve diagnosis of the disease. Methods: The imaging characteristics of 5 cases of hmea confirmed by histo-pathology were retrospectively analyzed. Results: All the 5 cases of HMEA were female. The main imaging findings were as follows: ① The lesions were low-density or medium density (signal), well defined, round or round-like, with size of 3. 7~9. 5 cm in diameters; ② On contrast-enhanced scan, the lesions appeared as obviously homogeneous enhancement in artery phase, and unhomogeneous enhancement in a few of cases. There were enlarged malformation vessels in the center or around the tumorsi ③ The enhanced mode of the lesions appeared as quick-in and quick-out or quick-in and slow-out and there were still malformation vessels that could be identified. Conclusion: The HMEA is more predi-lection to female, and has certain imaging characteristics. The final diagnosis of HMEA relies on histopatho-logical results.%目的:分析肝脏上皮样血管平滑肌脂肪瘤(HMEA)的影像学表现及其病理,以提高对该病的诊断水平.方法:回顾性分析5例经病理证实的HMEA的影像学表现及其病理.结果:5例均为女性,影像学特征有:①平扫呈低或稍高密度(信号),边缘光整,圆形或类圆形,大小约3.7～9.5cm;②增强扫描动脉期呈较明显或明显均匀强化,少数可不均匀明显强化,中央或周边可见粗大畸形的血管；③强化方式为快进快出或快进慢出、持续性强化,仍有畸形血管可以辨别.结论:HMEA多见于女性,其影像学表现具有一定特征,确诊仍有赖于病理组织学及免疫组织化学检查.
