Esophageal lung complicated by recurrent pneumonia.

A 6-month-old infant with recurrent respiratory infections, rapid breathing, and reduced air entry on the right side was diagnosed with congenital bronchopulmonary foregut malformation (CBPFM). Imaging revealed a collapsed and underdeveloped right lung, with the right bronchus appearing to originate from the lower part of the esophagus. An esophagogram confirmed the diagnosis by showing contrast flowing freely from the lower esophagus to the right bronchus.
