Primary congenital pulmonary hypoplasia of a neonate.

Pulmonary hypoplasia is a rare but usually lethal disease. We report a full-term male neonate who presented with respiratory failure immediately after birth. Chest X-ray revealed a small lung volume despite advanced ventilator support. Respiratory failure persisted and this baby died at 40.5 hours of age. The autopsy showed a lung-to-birth weight ratio of 0.69% and a radial alveoli count of 2.97. All this information confirmed the diagnosis of primary congenital pulmonary hypoplasia. Copyright Â
