MRI结合MRCP诊断肝门区胆管癌(附39例分析)

MRI and MRCP diagnosis of portal cholangiocarcinoma(analysis of 39 cases)

目的:探讨肝门区胆管癌MRI、MRCP表现及诊断价值。方法:分析总结了39例肝门区胆管癌的MRI和MRCP表现,并与手术病理结果对比。结果:39例肝门区胆管癌中,MRI均显示肝内胆管不同程度的扩张,其中肝门区软组织肿块34例,增强扫描均呈不均匀性强化,胆管壁不规则增厚呈鼠尾状5例。MRCP显示病变部位胆管中断,梗阻近端形态截断状或圆锥状17例,鸟嘴状或鼠尾状27例,杯口状2例。结论:MRI结合MRCP是检查肝门区胆管癌的有效手段。

Objective： To investigate the MRI and MRCP findings and diagnostic value in hilar cholangiocarcinoma. Metheds： MRI and MRCP appearances were analyzed and compared with the results of pathology and surgery in 39 cases with hilar cholangiocarcinoma.Resuits： Cases with hilar cholangiocarcinoma were found to have intrahepatic biliary duct dilation, with salt tissue mass at porta hepatis in 34 eases. The contrast enhancement scanning further found tumors in 34 cases. Five of 39 eases showed thickening of wall of bile duct only on MPI. MRCP found interrapted, abruptly cut-off or cone-like changes of the bile dutc in 17 cases, beak-like or mouse tail changes in 27 cases, tumbler mouth appearance in 2 cases. Conclusion： MPI and MRCP are valid methods in hilar ccholangiocarcinoma.
