[Abdomino-pericardial hernia as a result of an anomaly of the septum transversum. Apropos of a case in a newborn infant].

This is a case report of a peritoneo-pericardial diaphragmatic hernia revealed by a respiratory distress in a newborn infant. Radiography and angiocardiography allowed preoperative diagnostic and the patient was operated upon successfully on two days of age. Anatomic finding was a defect of the central tendon of the diaphragm with a hernial sac. This anomaly is rare and probably results from a misdevelopment of the septum transversum.
