title: Esophageal duplication cyst causing unilateral hyperinflation of the lung in a neonate.
abstract: Esophageal duplication cysts are rare congenital anomalies. Frequently asymptomatic, they may cause respiratory distress and feeding difficulties in infants. Unilateral hyperinflation of the lung due to compression of the bronchus by the cyst is rare. We report a case of a 4-day-old male neonate presenting with respiratory distress who had an esophageal duplication cyst causing obstructive hyperinflation of the right lung. The nature of the cyst was confirmed after surgery.
