目的探讨多层螺旋CT(MSCT)对肝外胆管细胞癌的诊断价值.方法回顾性分析27例经病理确诊的肝外胆管癌的临床资料及MSCT图像特征,20例行平扫及四期动态增强扫描(即早动脉期,晚动脉期,门脉期及延迟期),7例仅行增强扫描.结果肝门区胆管癌15例,胆总管癌12例;不同部位,不同生长方式的胆管癌CT表现各具特点,除延迟强化等直接征象外,肝叶萎缩,胆管扩张等间接征象亦具有特征性.结论多层螺旋CT对于肝外胆管细胞癌具有较高的诊断价值.

Objective To evaluate the value of MSCT in the diagnosis of extrahepatic cholangiocarcinoma.Methods The MSCT appearances of extrahepatic cholangiocarcinoma confirmed by pathology in 27 cases were analyzed retrospectively.Among them,20 patients underwent plain and four-phase dynamic contrast-enhanced CT scans including early arterial phase,late arterial phase,portal phase and delay phase,7 patients only underwent contrast-enhanced CT scans.Results 15 lesions were located in the hilar and 12 lesions were located in the common bile duct.CT features of cholangiocarcinomas in this group were varied with its position and growth pattern.Besides the direct sign such as delay enhancement,the indirect findings were also specific such as hepatic lobe atrophy,dilated bile duct,etc.Conclusion MSCT is of great value in diagnosis of extrahepatic cholangiocarcinoma.
