摘要:目的：研究周围型肝内胆管细胞癌的CT诊断及病理基础,提高对周围型胆管细胞癌的认识。方法：12例经病理证实周围型胆管细胞癌的常规CT平扫及CT增强扫描。结果：CT平扫所有病例为单发低密度病灶，其中10例病灶内和/或病灶周围见更低密度影，2例病灶内见钙化，增强扫描动脉期所有病例均见不均匀强化，门脉期11例病灶强化更明显，延迟期11例病灶均持续强化， 8例可见胆管扩张。结论：CT是周围型肝内胆管细胞癌的重要影像检查方法，门脉期进一步强化和延迟期持续强化以及病灶内和/或病灶周围胆管扩张是周围型肝内胆管细胞癌的重要征象。

    Abstract:Objective： Study CT diagnosing and pathology foundation of the intrahepatic peripheral cholangiocarcinoma. Improve the understanding of intrahepatic peripheral cholangiocarcinoma. Method： 12 are strengthened the scanning by routine CT flat sweeping and CT that pathology verify the intrahepatic peripheral cholangiocarcinoma. Result： It is flat for CT not to sweep all cases single shot low density focus, Among them see the lower density shadow in 10 focuses and/or around the focus. See the calcification in 2 focuses. Strengthen a case of scanning the artery to see and does not strengthen evently. A 11 focuses of door pulse strengthen more obvious. Delay 11 focuses to strengthen continuously. 8 can see bile duct to expand. Conclusion： CT is the important image inspection method of the intrahepatic peripheral cholangiocarcinoma. Door pulse issue strengthen and delay issue not to strengthen continuously further and in the focus and/or bile duct. it expands to be important sign of intrahepatic peripheral cholangiocarcinoma around the focus. ......
