A patient with hepatic epithelioid angiomyolipoma (Epi-AML) with arterioportal venous shunting, who was successfully treated by a laparoscopic left lateral sectionectomy, is presented herein. AML is an uncommon benign neoplasm of the liver. Tumors composed predominantly of epithelioid cells have been subcategorized into Epi-AML, and the treatment strategy for Epi-AML is currently undetermined. There are no reports describing Epi-AML with arterioportal venous shunting to date. An arterioportal venous shunting of the liver tumor was suggested to be one of the malignant signs of the liver tumor. It would be important to differentiate Epi-AML with arterioportal venous shunting from hepatocellular carcinoma and hypervascular metastatic tumors. Minimally invasive resection, such as laparoscopic hepatectomy, for patients having Epi-AML with arterioportal venous shunting may be recommended.
本文介绍了一名患有肝上皮样血管平滑肌脂肪瘤（Epi-AML）并伴有动门静脉分流的患者，该患者通过腹腔镜左外侧叶切除术成功治愈。AML是一种罕见的肝脏良性肿瘤。主要由上皮样细胞组成的肿瘤已被归类为Epi-AML，目前Epi-AML的治疗策略尚未确定。迄今为止，尚无关于伴有动门静脉分流的Epi-AML的报道。肝脏肿瘤的动门静脉分流被认为是肝脏肿瘤的恶性征象之一。将伴有动门静脉分流的Epi-AML与肝细胞癌和高血运转移瘤区分开来很重要。对于患有伴有动门静脉分流的Epi-AML的患者，可能推荐进行微创切除，如腹腔镜肝切除术。
