Definition
=========================================================================

● Arises from ectopic foregut; buds of developing embryonic lung become separated from the tracheobronchial tree before bronchi are formed, and may be lined by squamous, ciliated, or columnar epithelium
● May be intrapulmonary or extrapulmonary and are almost always independent of bronchi
● Relatively rare; most common site is posterior mediastinum at level of carina (eMedicine)
● Present as space occupying lesion, may compromise airway
