肝内胆管细胞癌的MSCT诊断价值

目的探讨肝内胆管细胞癌的MSCT诊断价值及鉴别要点。方法回顾性分析经手术病理证实的15例肝内胆管细胞癌的MSCT表现。结果病灶单发14例,多发1例;肝左叶12例,肝右叶3例;大小3.5～8.5cm,平均5.8cm。平扫:低密度13例,不规则形11例,边缘不清12例。增强扫描:动脉期强化不明显10例,门脉期环形强化12例,呈渐进性和向心性轻中度强化,延迟期持续强化,病灶强化高于肝实质10例。肝内胆管扩张5例,肝内胆管结石3例,肝叶萎缩3例,局部肝轮廓凹陷2例。结论肝内胆管细胞癌的MSCT多期增强表现有较明显的特征性,具有较高的诊断和鉴别诊断价值。

Diagnositic Value of Multi-slice Computed Tomography in Intrahepatic Cholangiocarcinoma

Objective To investigate the MSCT diagnostic value and differential diagnosis of the intrahepatic cholangiocarcinoma.Methods The MSCT features of 15 cases by surgically and pathologically confirmed intrahepatic cholangiocarcinoma were reviewed retrospectively.Results Single lesion in 14 cases,multiple lesions in 1 case;left lobe of liver in 12 cases,right lobe of liver in 3 cases;the size of 3.5 ~ 8.5cm,an average of 5.8cm.Plain scan：low density in 13 cases,irregular shape in 11 cases,the edge unclear in 12 cases.Enhanced Scanning：enhanced arterial phase was not obvious in 10 cases,ringenhanced portal venous phase in 12 cases,showed progressive and concentric with mild to moderate enhancement,delayed phase continued to strengthen,the lesions enhance more than 11 cases of liver parenchyma.Expansion of intrahepatic bile duct in 12 cases,intrahepatic bile duct stones in 8 cases,8 cases of hepatic lobe atrophy and partial liver contour depressions in 6 cases.Conclusion Enhance the performance of multi-phase MSCT of intrahepatic cholangiocarcinoma has a more obvious characteristic,with high diagnostic and differential diagnostic value.
