肝门胆管癌的CT诊断价值探讨

CT Diagnosis of Cholangiocarcinoma in Porta Hepatis

目的探讨肝门胆管癌的CT诊断价值及病理基础。方法本文收集21例均经手术及病理证实的肝门管癌,行CT平扫及增强双期扫描,21例均加做CT延迟扫描。结果①胆管扩张14例;②21例肝门胆管癌动态扫描,呈低密度13例,等密度6例,高密度2例;③延迟扫描,呈相对高密度18例,等密度3例,无低密度,肿瘤边界更明确。结论CT是诊断原发性肝门胆管癌有效、准确的检查方法。

Objective To investigate the CT features and pathologic basis of cholangicocareinoma in porta hepatis. Methods Plain scan, dual-phase scan and delayed scan were performed in21 cases of hepatic porta cholangicocarcinoma confirmed pathologically. Results （1）Dilatation of hepatic porta biliary tracts were discovered in 14 cases;（2）On early CT scan, the masses appeared hypodense in 13 cases,isodense in 6 cases, and hyperdense in 2 cases; （3）on delayed scan, the masses with more clear demarcation appeared hyperdense in 18 casse,isodense in 3 cases,andhypedense in zero cases.Conclusion It suggested that CT scan is an effective and accurate technique in diagnosis of hepatic porta cholangicocaricnoma.
