Elucidating the anatomy of a rare communicating bronchopulmonary foregut malformation (CBPFM) in a preschool child.

Communicating bronchopulmonary foregut malformations (CBPFMs) are complex and rare anomalies. Their characteristic feature is an anomalous communication between the respiratory system (trachea, lung or bronchus) on one side and the gastrointestinal tract (oesophagus or stomach) on the other. Though acquired CBPFMs are known, the large majority of them are congenital and single.
