摘    要:目的:探讨外伤性肝内胆汁瘤的CT与MRI表现特征。方法:回顾性分析10例临床证实的外伤性肝内胆汁瘤的影像资料。结果:全部病例有CT检查资料,2例病程中行MRI检查。全部病例伴肝实质挫裂伤,外伤后短期内CT或MRI检查提示肝内大片状低密度或长T1长T2信号影,随访中很快出现水样密度或信号影。其中囊状单发7例,多发3例。多发者沿胆管树呈囊袋状排列。除7例随访中渐小外,其余3例均经手术或超声或CT引导下引流治愈,其内容物均为胆汁成分。结论:认识外伤性肝内胆汁瘤CT与MRI表现特征对于诊断及进一步治疗具有重要意义。

Abstract:Objective:To investigate the features of traumatic intrahepatic biloma on CT and MRI.Methods:The imaging data of 10 patients with traumatic intrahepatic biloma clinically confirmed were analyzed retrospectively. Results:All patients underwent CT examination,2 cases underwent MRI examination in the course of the disease. All with hepatic parenchymal laceration,a short period of trauma,it showed low-density or large sheet long T1, long T2 signal intensity,follow-up soon showed water density or signal intensity in liver on CT and MRI.7 cases were single cystic,multiple in 3 cases.Multiple biloma along the biliary tree were pouch pocket arrangement. Except for 7 cases were naturally smaller,the remaining 3 cases were cured by surgery or ultrasound or CT-guided drainage,and whose contents were bile components.Conclusion:It has crucial significance for the diagnosis and treatment to recognize the CT and MRI features of traumatic intrahepatic biloma.
Keywords:liver injury  biloma  tomography  X-ray computed  magnetic resonance imaging
