Transient, physiologic and rare, dilatation of the ductus arteriosus in asymptomatic neonates, shown by left superior mediastinal mass. It appears only on the PA chest roentgenogram, with vascular characteristics. It disappears after three or four days of regular checking and the diagnosis is thus confirmed, cutting out any other mediastinal pathology. There is no need to use more stressing or ruder technics.
无症状新生儿动脉导管的短暂、生理性且罕见的扩张，表现为左上纵隔肿块。仅在胸部后前位X线片上可见，具有血管特征。经定期检查，三四天后消失，从而确诊，排除了任何其他纵隔病变。无需采用更具侵入性或粗暴的检查方法。
