Anomalous continuation of the inferior vena cava with an azygous vein is a rare vacular anomaly. The enlarged venous system may simulate adenopathies or mediastinal and retroperitoneal masses on the radiographs. We describe the case of a patient with lung cancer - a pathological condition which may cause adenopathies at these sites - and a dilated azygous-hemiazygous system resulting from failure of formation of the hepatic segment of the inferior vena cava.
下腔静脉与奇静脉异常延续是一种罕见的血管异常。在X线片上，扩大的静脉系统可能类似淋巴结肿大或纵隔及腹膜后肿块。我们描述了一例肺癌患者的病例——肺癌是一种可能导致这些部位淋巴结肿大的病理状况——以及因下腔静脉肝段形成失败导致的奇静脉-半奇静脉系统扩张。
