[Margagni-Larrey diaphragmatic hernia. Description of a clinical case]

A clinical case report of a Morgagni-Larrey hernia is presented. The finding was made at the age of four months by means of x-ray of the thorax, performed because of recurrent respiratory symptoms regressed after surgical intervention. The rarity of this type of hernia, without a herniary sac and accompanied by the late appearance of respiratory symptomatology, is stressed. It is suggested that x-ray of the thorax should be performed when recurrent respiratory disease is the presenting complaint, even in the first few months of life.
