Summary

Eventration of diaphragm is an uncommon disorder in which diaphragmatic muscle is replaced by fibroelastic tissue, either partially or completely. Bilateral eventration is even rarer. We present a case of bilateral eventration of diaphragm in newborn with a fibroelastic sac on left side and diaphragmatic eventration with good muscular lips on right side. The right-sided diaphragmatic eventration was not evident initially, but manifested after surgical repair of the left-sided eventration.
