BRONCHOGENIC CYSTS

Bronchogenic cysts result from abnormal budding of the ventral foregut diverticulum between 26 and 40 days of embryogenesis (this is the most active period for tracheal and bronchial development) (1). Respiratory epithelium lines the cyst and the walls contain mucous glands, cartilage, elastic tissue and smooth muscle (1-9).

 

LOCATION

  1. Mediastinum Bronchogenic Cyst
  2. Intrapulmonary Bronchogenic Cyst
  3. Ectopic intra-abdominal bronchogenic cyst has been described (10). Other ectopic locations include the cervical and retroperitoneal regions.
