Bronchiectasis is a lung disease which causes frequent cough and phlegm, along with repeated infections that may lead to permanent damage of the lungs.
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.
