Agenesis of right diaphragm in the adults: a diagnostic dilemma.

Diaphragmatic agenesis is the most extreme form of congenital diaphragmatic defect, and it may be unilateral or bilateral. Diaphragmatic agenesis is a rare diagnosis, typically made early in infancy and is generally associated with other genetic anomalies, especially anueploidy syndromes. It is associated with a high mortality, if not treated in infancy.
