【摘要】 目的 探讨周围型肝内胆管细胞癌的CT表现及与其他肝内肿瘤的鉴别要点。方法 回顾性分析经手术病理证实的24例周围型肝内胆管细胞癌的CT资料。结果 24例患者中，18例为单发病灶，大小为3～10cm，6例为多发大小不一病灶，肝内胆管扩张12例，肝内胆管结石8例，肝叶萎缩8例，局部肝轮廓凹陷6例。增强扫描可见动脉期和静脉期边缘轻度强化，且不同程度出现线样和网格状强化，延迟扫描，随着时间的延长病灶逐步由边缘向中心强化，最后病灶强化高于肝实质，延迟扫描的表现有一定的诊断价值。结论 周围型胆管细胞癌的CT表现具有一定的特征性，大多可以和肝内其他占位病变鉴别，其中又以螺旋CT多期增强扫描具有较高的诊断价值。
