title: Agenesis of the right upper lobe.
abstract: Bronchoscopy and bronchography revealed a very rare abnormality in the embryonal anatomy of the right bronchial tree in a 54-year-old woman with cough. There was a proximal migration of the apical branch of the right upper bronchus toward the trachea and a distal migration of the two other branches toward the middle lobe bronchus. The proximal migration was accompanied by a narrowing of the trachea. This case is considered an extremely rare embryonal variation in the development of the right bronchial tree.
