A rare case of esophageal lung in a neonate

We report a rare case of esophageal lung in a neonate who presented with repeated chest infections and respiratory distress. Chest radiograph revealed increased opacification of the right lung with reduced lung volume and air bronchograms. Further evaluation with computed tomography (CT) showed the presence of only left mainstem bronchus at the tracheal bifurcation. Right mainstem bronchus originated from distal esophagus and aerated the right lung. Nasogastric tube was inserted into the stomach with injection of small amount of dilute barium through it, which established the communication of right mainstem bronchus with esophagus. Advanced CT scan imaging by virtual bronchoscopy and volume rendering further delineated the anatomical abnormality precisely prior to surgery. Surgical findings confirmed the diagnosis.
