title: [The ductus bump. Transient dilatation of the ductus arteriosus (author's transl)].
abstract: 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.
