Pulmonary vein varix is an unusual cause of a mediastinal mass on a chest radiograph. It may be found as an isolated malformation or as a sequela of pulmonary venous hypertension. We encountered a case presenting with left hemiparesis and a past medical history of rheumatic heart disease. The chest radiograph revealed a well-defined mediastinal mass that turned out to be a hugely dilated pulmonary vein on contrast enhanced computed tomography of the chest. The computed tomography of the brain and upper abdomen revealed bilateral cerebral infarction and splenic infarction. In the literature, one-third of the reported cases of pulmonary vein varix are acquired secondary to mitral valve disease.
肺静脉瘤样扩张是胸部X线片上纵隔肿块的一种不常见病因。它可能作为一种孤立的畸形出现，也可能是肺静脉高压的后遗症。我们遇到一例表现为左半身轻瘫且有风湿性心脏病病史的病例。胸部X线片显示一个边界清晰的纵隔肿块，胸部增强计算机断层扫描结果显示其为极度扩张的肺静脉。脑部和上腹部的计算机断层扫描显示双侧脑梗死和脾梗死。在文献中，报道的肺静脉瘤样扩张病例中有三分之一是继发于二尖瓣疾病。
