| 摘 要： | 目的 分析周围型肝内胆管细胞癌的直接和间接CT征象.方法 回顾性分析92例经手术病理证实的周围型肝内胆管细胞癌的CT平扫及增强资料,分析病变分型,病灶部位、大小、增强强化时间-密度曲线、局部胆管扩张、肝包膜局限性凹陷以及是否伴有胆道结石,结合病理进行对照分析和统计.结果 92例肝内胆管细胞癌位于肝左叶57例,肝右叶35例.病灶大小为2.5～ 12cm,平均为6.5cm.CT平扫病灶均为低密度,CT值平均为41 Hu.增强扫描动脉期和门脉期呈不规则轻度晕圈状强化,境界不清,延迟期内部可见线样及条网状强化,平均CT值分别为63 Hu、74Hu和79Hu.延迟5分钟扫描病灶均呈进一步强化,平均CT值为82 Hu,时间-密度曲线呈＂缓慢上升-平台＂型.89例为单发病灶,3例为多发病灶融合,肝内胆管扩张35例,肝内胆管结石31例,肝叶变形萎缩33例,局部肝包膜凹陷29例.结论 周围型肝内胆管细胞癌的直接CT征象是延迟强化的肝内肿块,缓慢上升-平台型时间-曲线是其特征强化规律,病灶周围胆管扩张和包膜凹陷是其重要的间接征象.

| Abstract: | Objective To investigate the direct and indirect MDCT findings in patients with peripheral intrahepatic cholangiocarcinoma (PICC).Methods 92 cases with PICC underwent CT plain and enhanced scan were analyzed retrospectively which confirmed by surgery and pathology.CT findings including lesion types,location and size of lesions,the enhanced time-density curves of lesions,biliary dilatation,localized excavation of liver capsule,biliary stones were analyzed.Statistical analysis was done combined with pathology... |
