Delayed onset of left-sided diaphragmatic hernia in a newborn

Congenital diaphragmatic hernia usually causes severe respiratory distress presenting in the first hours of life. There is, however, a group of patients who may be asymptomatic during the perinatal period, but manifest the abnormality after days, weeks and even years. We report a delayed onset of left-sided diaphragmatic hernia in a three weeks old newborn with a favourable prognosis.
