The utility of CT virtual bronchoscopy in the esophageal lung diagnosis: A case report.

The esophageal lung is a variant of the communicating bronchopulmonary foregut malformation (CBPFM). It needs a high index of suspicion for diagnosis because it is a rare condition and does not have specific symptoms. A CT scan or an esophageal contrast study, showing direct communication between the airways and the esophagus or stomach, confirms the diagnosis. Patients with esophageal lung need flexible bronchoscopy for evaluating tracheobronchial anomalies. We present a three-month-old boy with a right esophageal lung in which the CT virtual bronchoscopy showed an absence of the right main bronchus at the carina level. This case report highlights the importance of CT virtual bronchoscopy as an alternative to flexible bronchoscopy for the diagnosis of tracheobronchial anomalies associated with CBPFM.
