目的：探讨肝内胆管细胞癌的CT表现及其诊断价值。方法对28例经手术或穿刺活体组织检查经病理证实为肝内胆管细胞癌患者的CT表现进行分析。结果28例肝内胆管细胞癌患者的30个病灶CT平扫均为低密度，病变区或其周围见胆管扩张，其中15例见肝包膜回缩征，11例为肝内胆管结石术后。增强扫描动脉期病灶边缘环形增强9例。门静脉期11例中央网格样增强。延迟期8例呈向心性增强,密度略高于正常肝实质。结论肝内胆管细胞癌CT表现具有一定特异性,有利于肝内胆管细胞癌诊断。

Objective To evaluate the CT value in diagnosis of intrahepatic cholangiocarcinoma. Methods CT findings for intrahepatic cholangiocarcinoma of 28 cases that was confirmed by operation or biopsy pathologically were analyzed. Results Twenty-eight cases of intrahepatic cholangiocarcinoma patients with 30 lesions underwent plain CT scan and it showed low density lesions, or common bile duct dilatation around. Of them there were 15 cases with retraction of liver capsule, 11 cases of intrahepatic bile duct stones after operation. For 9 cases, the edge of le-sions was ring-like enhancement in arterial phase by enhanced scanning lesions. And there were 11 cases of central reticular enhancement in portal vein phase, 8 cases were concentric enhanced in the delay period with the density slightly higher than that of normal liver parenchyma. Conclusion Intrahepatic cholangiocarcinoma CT have certain specificity, which is in favor of intrahepatic cholangiocarcinoma diagnosis.
