摘　　要：目的:分析肝外胆管细胞癌的CT表现,探讨其诊断价值。材料和方法:23例病理证实的肝外胆管癌均行螺旋CT动态增强检查和ERCP检查,分析其影像表现和诊断准确性。结果:CT诊断符合率78.3%(18/23),均表现为特征软组织肿块(直接征象)和肝内胆管及胆总管扩张(间接征象)。CT同时提供了较好的肿瘤分期诊断。ERCP诊断符合率91.3%(21/23),表现为肝内胆管均呈不同程度的扩张,肝外胆管狭窄、截断。CT结合ERCP后全部诊断正确,并提供详细信息。结论:肝外胆管细胞癌的螺旋CT检查有较好的诊断,结合ERCP可以获得更高的诊断准确率。Purpose： To analyze the CT findings of extrahepatic cholangiocarcinoma（EC） and evaluate its diagnostic value. Materials and Methods： Twenty - three patients who were diagnosed EC by pathology were undergone the dynamic enhanced CT scan and endoscopic retrograde cholangiopancreatography（ERCP）, The findings and the diagnostic accuracy of the examination were evaluated. Results： A correct CT diagnosis was found in 18 patients（78.3%）, who all showed the characteristic soft tissue mass（direct sign） and dilation of bile ducts（indirect sign） . A good CT staging diagnosis was obtained in the mean time. A correct ERCP diagnosis was found in 21 patients（91.3% ）, who showed dilation of intrahepatic bile ducts and Stricture or cut - off of extrahepatic bile duct. Combination of CT and ERCP provided the correct diagnosis in all patients and also the detail information. Conclusion： The EC could be well diagnosed with spiral CT scan,and better diagnosed combining with ERCP examination.
