【摘要】 目的分析胆管细胞癌的CT表现,提高对胆管细胞癌的认识。方法回顾性分析经病理证实的21例胆管细胞癌的CT表现。结果CT平扫所有病例均为单发低密度灶。CT增强扫描21例不均匀轻度强化,其中4例出现大片无强化低密度区,部分边缘强化,2例病灶延迟强化,17例肝内胆管扩张。结论CT是胆管细胞癌的重要影像检查方法,不均匀强化病灶内可见胆管扩张是胆管细胞癌的重要征象。更多还原

【Abstract】 Objective To analyse CT appearances of intrahepatic cholangiocarcinoma,and to improve the understanding of intrahepatic cholangiocarcinoma.Methods CT appearances of intrahepatic cholangiocarcinoma proved by histologically in 21 cases were retrospectively analyzed.Results The lesions appeared as single low density in all cases on plain CT scan,post-contrast CT scanning showed slightly inhomogeneous enhancement in 21 patients,4 patients showed unenhanced low density area with marginal enhancement,2 patients had delayed enhancement.Intrahepatic billary dilatation was found in 17 patients.Conclusion CT scan is an important imaging methods in diagnosis of intrahepatic cholangiocarcnoma,the billary dilatations with slightly inhomogeneous enhancement is an important sign in diagnosing intrahepatic cholangiocarcinoma.更多还原
