摘　　要：本文对５６例经手术和病理证实的肝门部胆管癌进行了影像学回顾性分析，直接法胆道造影（ＤＣ）表现征象可分为胆道梗阻、狭窄、息肉样变和右肝管狭窄伴左肝管梗阻。ＵＳ显示肝内胆管的扩张，肝门区低回声占位，胆管内低回声肿块，门静脉癌栓。ＣＴ可表现，肝内胆管扩张，肝门区软组织密度肿块，肝门区肿块有增强，胆囊变小或萎缩，左肝萎缩和右肝增大，作者认为：ＤＣ加上ＵＳ或ＣＴ是诊断肝门区胆管癌的首选方法。The imaging features of 56 cases of porta hepatis cholangiocarcinoma with surgical and pathological confirmations were reviewed.Under direct cholangiography(DC)the features could be classified into obstructive,stenotic, polypoid and right hepatic duct stenosis with left hepatic duct obstructive types.US demonstrated interhepatic ducts dilatation, hypoechoic solid mass in porta hepatis, hypoechoic space-occupying lesion in bile duct and tumor thrombus of portal vein. CT showed interhepatic ducts dilatation, a soft tissue density mass in the porta hepatis, with contrast enhancement mass in porta hepatis,atrophy of gallbladder, hypertraphy of right hepatic lobe and atrophy of left hepatic lobe.It was believed that DC with U S or CT were the method of choice in dealing with porta hepatis cholangiocarcinoma.
