摘　　要：目的：加深对肝外胆管癌ＣＴ表现的认识，探索ＣＴ对肝外胆管癌的检查方法。方法：分析２１例经手术病理或活检证实的肝外胆管癌的ＣＴ表现，其中肝门部胆管癌３例，胆总管癌１８例。１２例梗阻端行薄层放大增强扫描。结果：３例肝门胆管癌肝内胆管均扩张，２例肝门区可见肿块。１８例胆总管癌均见扩张胆总管突然中断或变形，３例梗阻近端胆管壁不均匀增厚，５例腔内见软组织结节影，５例出现明显侵犯到腔外的软组织肿块影。结论：ＣＴ薄层放大增强扫描能有效地显示梗阻端形态，是诊断肝外胆管癌有效而较可靠的方法。Objective：To improve the knowledge of CT findings of extrahepatic biliary carcinoma,and to investigate the technique of CT scanning in the detection of extrahepatic biliary carcinoma.Methods：CT findings of 21 patients with surgically and pathologically proved extrahepatic biliary carcinoma, including hepatic hilar cholangiocarcinoma in 3 cases and common bile duct(CBD) cholangiocarcinoma in 18, were analyzed.The obstructed site in 12 of 21 cases were performed additional enhanced CT scanning with thin section and magnification.Results：Intrahepatic bile duct was dilated in 3 cases of hilar cholangiocarcinoma, and the mass in hepatic hilum was seen in 2 of them.Dilated CBD was suddenly interrupted or deformed in 18 cases of CBD cholangiocarcinoma,3 of them also revealed the unevenly thickened wall in proximal end of the obstruction. Intraductal soft tissue node was shown in 5 cases and invasion of extraductal soft tissue in 5.Conclusion：Enhanced CT scanning with thin section and magnification will be able to show effectively the shape of the obstructed site of biliary duct.It is an effective and reliable method for the diagnosis of extrahepatic cholangiocarcinoma.
