Abstract
回顾性分析2015年1月至2018年12月郑州大学第一附属医院病理确诊的9例肝血管周上皮细胞肿瘤(PEComa)患者，对其临床诊疗和预后进行分析。患者随访5.0～51.0个月，1例患者穿刺活检未进一步治疗，出院后6个月因肾脏肿瘤破裂死亡，另8例手术切除患者未发现肿瘤复发及转移。肝PEComa以女性多发，临床症状不典型，可伴腹痛、腹胀不适、食欲减退、发热、体重减轻。肝PEComa常单发，以肝右叶多见。术前完善影像学检查可协助诊断，CT平扫肿瘤呈均匀低密度或不均匀混杂密度，增强扫描动脉期表现为明显不均匀强化。肝PEComa以手术切除为主，良性首选手术治疗且预后良好，恶性需综合治疗。
