肝门胆管癌的CT诊断

CT Diagnosis Of Cholangiocarcinoma In Porta Hepatis

目的评价螺旋CT对肝门胆管癌的诊断价值。方法回顾性分析经手术及病理证实的32例肝门胆管癌的CT平扫和动态增强影像表现特征。结果32例均有程度不同的胆管扩张,其中27例平扫表现肝门区低或略低密度影:增强扫描呈高密度4例、等密度13例、略低密度10例,延迟扫描呈相对高密度28例、等密度4例、无低密度,肿瘤边界更明确。结论螺旋CT是诊断肝门胆管癌有效、准确的检查方法。

Objective To asses the value of spiral CT in the diagnosis of hilarcholangiocarcinoma.Methods 32 cases of hepatic cholangiocareioma by surgically and pathologically were collected.Analyse the characters of CT plain and dynamic enhanced scan.Results Dilatation in different degree of hepatic porta biliary tracts were discovered in 32 cases.On plain scan,the besions appeared as soft tissue mass with low density in hepatic hilar（n=27）.On early CT scan,appeared hyperdense in 4 cases,isodense in 13 case,hypodense in 10 cases;on delayed scan,the masses with more clear demarcation appeared hyperdense in 28 cases,isodense in 4 case,and hypodense in zero case.Conclusion It suggested that spiral CT scan is an effective and accurate technique in diagnosis of hepatic porta cholangicocaricnoma.
