A mediastinal tumour was simulated by gross dilatation of the azygos vein resulting from compression by enlarged hilar lymph nodes at the point where it crossed the right main bronchus to enter the superior vena cava. This cause of dilatation of the azygos vein has not previously been reported. Published reports are reviewed and attention drawn to the large proportion of patients (11/19) with this condition who had needless thoracotomies. The possibility of making a diagnosis by means of clinical observation and simple radiological techniques and thus avoiding surgical intervention is discussed.
肿大的肺门淋巴结在奇静脉穿过右主支气管进入上腔静脉处对其造成压迫，导致奇静脉显著扩张，从而模拟出纵隔肿瘤。奇静脉扩张的这一病因此前未见报道。本文回顾了已发表的报告，并提请注意有很大比例（11/19）患有这种疾病的患者接受了不必要的开胸手术。文中讨论了通过临床观察和简单的放射学技术进行诊断从而避免手术干预的可能性。
