Retrocardiac pneumomediastinum was encountered in two premature infants; one had a tracheal perforation and one an esophageal perforation. Contrast studies showed communication between the sites of perforation and the retrocardiac air. Clinical signs suggestive of such perforation include abnormal course of tubes on plain chest films and bloody aspirates.
