目的　探讨镰状韧带引起假性病灶的影像学表现，以提高对其的认识，减少误诊。方法　对2010年1月－2012年1月收入的817例患者进行上腹部64排CT平扫加增强扫描，筛选出肝镰状韧带附近假病灶，详细记录其部位、大小、形状以及扫描各期图像的密度变化情况。结果　有72例存在镰状韧带假病灶，绝大多数位于肝左叶内侧段（69例），并呈单发病灶（70例）。假病灶最大直径约5.1～22.0 mm，平均约13.1 mm，假病灶分别呈三角形43例、类圆形19例、结节状10例。CT扫描：平扫显示10例，动脉期显示63例，门脉期几乎全部显示清晰。结论　镰状韧带形成假病灶比较少见，其发生部位特殊，在门脉期易于显示，可与肝内真性病灶鉴别，以免误诊。
