Mediastinal pseudotumors are present in less than 5% of patients with long-standing portal hypertension. These pseudotumors may be caused by para-esophageal collateral vessels or greatly dilated azygos or hemiazygos veins. Enhanced CT seems to be the best tool for the diagnosis and in evaluating the overall status of portosystemic collateral vessels. In this case report, MRI ruled out tissular mass by showing vascular signal.
纵隔假瘤在长期门静脉高压患者中的发生率不到5%。这些假瘤可能由食管旁侧支血管或极度扩张的奇静脉或半奇静脉引起。增强CT似乎是诊断和评估门体侧支血管整体状况的最佳工具。在本病例报告中，MRI通过显示血管信号排除了组织肿块。
