周围型肝内胆管细胞癌的CT诊断及病理基础研究

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.

The Diagnosis of Intrahepatic Peripheral Cholangiocarcinoma by CT with the Correlation of Pathological Findings

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.
