摘要 目的探讨肝脏血管平滑肌脂肪瘤(HAML)的临床、影像学及病理学特点以及治疗、预后。方法对我科1988年6月至2011年6月收治的19例经手术治疗的HAML患者临床资料作回顾性分析。全部患者均行超声及CT检查,8例同时行MRI检查。所有患者均行肝切除术,并经病理及免疫组化确诊,均获随访。结果无临床症状者13例。B超多显示为不均质高回声光团,彩色多普勒显示点状、短线状彩色血流。19例CT平扫中6例测得CT负值(-43~-20HU),18例动脉期明显不均质强化,4例门脉期延迟强化。病灶由不同比例的厚壁血管、平滑肌细胞及脂肪混合组成。免疫组化染色结果显示,19例HMB-45表达均阳性。所有患者手术切除后随访无复发。结论 HAML临床表现无特殊,影像学表现多样;术前明确诊断较困难,误诊率高;确诊有赖于病理及免疫组化检查,HMB-45、SMA检测阳性有助于确诊。手术切除HAML可获得满意效果。
