原发性肝癌侵犯胆道的CT特征及病理对照研究

Characteristics of CT in primary hepatocellular carcinoma invading bile duct and its clinicopathological study

目的分析原发性肝癌侵犯胆道的CT表现,以提高该病的CT诊断符合率。方法收集经手术证实的原发性肝癌侵犯胆道病人21例,将其CT检查结果与同期的非黄疸型肝癌相比较。结果发现肝内原发病灶18例,肝内外胆管扩张21例,胆总管内异常密度影10例。结论CT检查可作为诊断肝癌侵犯胆道的重要手段。

Objective In order to in crease the diagnostic accurate rate of primary hepatocellular carcinoma invading bile duct,the CT findings of such patients were analysed.Methods The21cases with bile duct metastasis of primary hetatocellular carcinoma,which were proved by operation,were collected,the CT findings were analyzed and compared with other types of hepatocellular carcinoma at same stage.Results The primary liver cancer focus were found in18patients,bile duct dilatation in-oroutside liver in21patients,abnormal image inside common bile duct in10patients.The diameter of bike duct distended in all the patients.Conclusion CT would be taken as an important method for de-tecting bile duct metastasis of hepatocellular carcinoma.
