Mediastinal bronchogenic cysts.

It was observed from the literature that the incidence, clinical and radiological features of the mediastinal bronchogenic cysts are different in adults than in infant population. Five cases of bronchogenic cysts in the middle mediastinum were studied over a period of 22 years. The cysts were carina-based in four cases and paratracheal in one case. The airway compression was observed in four cases due to cysts. In case one the cyst compressed the right pulmonary artery and vein as well as both mainstem bronchi causing their stenosis and bulged into the left atrial chamber.
