肝脏胆汁瘤的MSCT表现及临床意义

摘要

Objective To investigate MSCT sings, etiology and clinical significance of intrahepatic biloma. Methods 16 patients with intrahepatic biloma confirmed by MSCT and clinic were retrospectively analyzed. All cases underwent multi-slice spiral CT scanning. Results Among 16 cases,8 cases were in company with hepatocellular carcinoma after transcatheter arterial chemoembolization (TACE, more than one time), 4 cases were in company with hepatic rupture, 2 cases presented after partial resection of hepatic and 2 cases presented after acute pancreatitis. MSCT sings of intrahepatic biloma appeared as single or multiple shadow with density of the fluid, the lesions were different size and various forms (cystic, columnar, branch, irregular ). Multi-plane reformation (MPR)couldexactly display the relationship between the biloma and intrahepatic bile duct. Conclusion The intrahepatic biloma can be accurately diagnosed in localization and qualitative analysis by MSCT.%目的 探讨肝脏胆汁瘤的MSCT表现、形成机制及临床意义.方法 搜集本院经MSCT检查及临床确诊的胆汁瘤16例,进行回顾性分析,16例均采用多层螺旋CT(MSCT)检查.结果 16例中原发性肝癌经TACE治疗后(每名患者均有1～7次的TACE治疗史)并发胆汁瘤8例,肝脏损伤破裂并发胆汁瘤4例,肝脏部分切除术后并发胆汁瘤2例,急性胰腺炎后并发肝内胆汁瘤2例.MSCT表现为肝内单发或多发、大小不一的囊状、柱状、分支状、不规则状的液性密度影,MPR准确显示胆汁瘤与肝内胆管的关系.结论 MSCT多平面重组(MPR),可以对胆汁瘤进行准确的定位与定性.
