Oesophageal lung: a rare cause of complete hemithorax opacification.

Congenital bronchopulmonary foregut anomalies are uncommon group of disorders that reflect upon the embryological development of the foregut. These conditions represent the intimate embryological proximity of the foregut and tracheobronchial tree. The radiological findings are typically of segmental or lobar consolidation with abnormal vascular supply or foregut communication. We report a case of a breathless neonate with oesophageal origin of the right main bronchus. This communication was well demonstrated with the help of an oesophagogram. The radiologist plays an important role by identifying this communication on a CT done for non-resolving lung collapse. Contrast-enhanced CT of the chest is also useful in evaluating the vascular supply of the lung that helps in diagnosis and also directs treatment.
