周围型肝内胆管细胞癌的多排螺旋CT表现

Multi-slice Spiral CT Findings of Intrahepatic Peripheral Cholangiocarcinoma

摘要:

目的探讨多排螺旋CT(MSCT)对周围型肝内胆管细胞癌的诊断价值。方法回顾分析15例经手术、病理证实的周围型肝内胆管细胞癌的MSCT表现。结果15例胆管细胞癌中,多发11例;9例位于肝右叶,6例位于肝左叶;病灶大小为3.5~12.1 cm,平均6.8 cm。MSCT特征为:病灶以低密度为主的不规则肿块,内可见囊性更低密度区,病灶以边缘轻至中度强化为主,出现特征性的从周边到中心的向心性强化、延迟强化,呈慢进慢出表现,病灶周围肝内胆管轻度扩张,局部肝萎缩,肝包膜凹陷征。结论MSCT对周围型肝内胆管细胞癌的检出及诊断具有较高的价值。

Objective To study the Multi-slice spiral CT(MSCT) features of intrahepatic peripheral cholangiocarcinoma. Methods The MSCT findings of 15 cases with pathologically confirmed intrahepatic peripheral cholangiocarcinoma were analyzed retrospectively. Results Of all the 15 cases,11 were mutiple mass with a diameter of 3.5~12.1 cm,9 lesions distributed in right liver lobe and 6 lesion in left one.All lesions displayed hypodense mass with central cystic degeneration area and irregular shape.Most of the lesions d...
