Early Neonatal Pneumoperitoneum from Progressive Massive Tension Pneumomediastinum

Abstract

Three cases of early neonatal pneumoperitoneum as a result of progressive massive tension pneumomediastinum are described. The important roentgenographic features include massive pneumomediastinum located both above and behind the heart, absence of free peritoneal fluid, pneumothorax, and air in the stomach. Laparotomy should be avoided in this condition.
