Bronchocele

A bronchocele is a segment of bronchus that is filled with mucus and completely enclosed so the mucus cannot drain out. This segment is usually dilated. It is also referred to as bronchial mucocele.^[1] If there is no obstruction to the flow of mucus, it is called mucoid impaction of bronchus.^[2] A bronchocele results from obstruction of the bronchus. Overproduction of mucus can also contribute. Obstruction may occur due to scarring, a tumor, or congenital atresia.^[3]
