title: [Solitary azygos prolongation (author's transl)].
abstract: Azygos prolongation of the inferior vena cava is a congenital abnormality which is normally associated with a congenital cardiac lesion, abnormalities of the inferior caval system and, in some instances, abdominal heterotaxia. The authors report here a case which is exceptional in the sense that the azygos prolongation was isolated. Further radiological studies are essential in order to make the diagnosis following the discovery of a right-sided laterotracheal opacity on a plain chest film. Only five other cases were found in the literature.
