 Case 229 : Mediastinal bronchogenic cyst

Definition: Bronchogenic cysts are rare congenital malformations of ventral foregut development. They are usually located in the mediastinum and intrapulmonary regions.

They occur as a result of a developmental fault during the division and budding of the tracheobronchial tree in the embryonic period. Approximately 50% of all congenital lung malformations are pulmonary and mediastinal bronchogenic cysts (BC).
