[Case of retrosternal Morgagni-Larrey hernia].

Retrosternal hernia (Morgagni-Larrey) is the less frequent of diaphragmatic defects. Nevertheless its frequency is probably more elevated than commonly believed because very often there is a lack of symptoms. The clinical case which is referred has a typical presentation but it is outlined the difficult interpretation of routine chest x-rays, while a prompt diagnostic suspicion is not always present. Surgical repair is the discussed emphasizing the very good results within a virtual absence of recurrences.
