We report 3 cases of mediastinal pseudotumours in cirrhotic patients. In the 3 cases, plain chest X-ray showed regular homogeneous radiolucency superposed on cardiac shadow. Computerized tomography bolus injection, performed in 2 cases, was poorly contributive in one case. On the other hand, magnetic resonance imaging ensured the diagnosis in all 3 patients showing significant dilatation of the azygos vein and prominent esophageal varices connected with spontaneous abdominal portacaval shunts. These vascular mediastinal structures were well documented by frontal and sagittal spin echoes. Knowledge of such neovascular mediastinal pseudotumours may prevent the use of invasive investigations such as direct puncture or thoracotomy.
我们报告了3例肝硬化患者纵隔假瘤的病例。在这3例病例中，胸部X线平片显示心脏阴影上方有规则的均匀透亮区。2例患者进行了计算机断层扫描团注，其中1例贡献不大。另一方面，磁共振成像确诊了所有3例患者，显示奇静脉明显扩张以及与自发性腹部门腔分流相关的显著食管静脉曲张。这些纵隔血管结构通过正位和矢状位自旋回波得到了很好的记录。了解这种纵隔新生血管性假瘤可避免使用如直接穿刺或开胸等侵入性检查。
