目的　探讨周围型肝内胆管细胞癌的CT特征。方法　回顾性分析经手术及病理证实的 2 2例周围型肝内胆管细胞癌的CT表现 ,并与手术结果对照。结果　周围型肝内胆管细胞癌的CT表现为低密度不规则肿块 ,边界欠清 ,增强扫描肿瘤边缘实质部分轻中度强化。CT特点为 :双期CT增强扫描表现为特征性的从周边到中心的向心性强化 ;病灶周围肝内胆管轻度扩张 ;局部肝包膜回缩征象 ;出现延迟强化 ;病灶大片坏死 ,液化较完全。结论　肝内胆管细胞癌的CT表现有一定的特征性 ,对于与肝内其他常见病变的鉴别诊断有重要价值 Objective To investigate the CT features of peripheral intrahepatic cholangiocarcinoma. Methods The CT findings of 22 cases of peripheral intrahepatic cholangiocarcinoma confirmed by surgery and pathology were retrospectively analyzed and compared with the surgical results. Results The CT findings of peripheral intrahepatic cholangiocarcinoma were low density and irregular mass, the border was not clear, and the substantial part of the edge of the enhanced scan was mild to moderate enhancement. CT features: double-phase CT enhanced scan performance from the periphery to the center of the centripetal enhancement; lesion around the intrahepatic bile duct mild dilatation; local hepatic capsule retraction signs; delayed enhancement; lesions necrosis, liquefaction complete. Conclusion CT manifestations of intrahepatic cholangiocarcinoma have certain characteristics, which are of great value in the differential diagnosis of other common intrahepatic lesions
