Bronchogenic Cysts

Bronchogenic cysts are abnormal growths of tissue that are congenital (present from birth). They typically have thin walls and are filled with fluid or mucous. Most bronchogenic cysts are found in the mediastinum, the part of the chest cavity that separates the lungs.


Many bronchogenic cysts produce no symptoms and are diagnosed during a test for another reason. Symptoms can develop if the cyst grows large enough to press on parts of the airway, or the esophagus, or if the cyst becomes infected. Symptoms of bronchogenic cysts include fever from infection, vague respiratory problems, and trouble swallowing.


The cause of bronchogenic cysts is unknown.

After a careful evaluation of the condition, the physician will recommend the treatment that is most appropriate. The goal of bronchogenic cyst treatment is to remove the cyst, which is called resection. There are several types of mediastinal tumor resection for cysts, including:
