Abstract: We report a case in which bronchial atresia in an accessory lobe caused tension pneumothorax. The atretic
bronchus was found in an accessory lobe (right S6) that had been incompletely isolated from the right lower
lobe during the fetal period. The accessory lobe was overinflated, leading to bullous formation due to the
trapping of air. Video-assisted excision of the posterior lobe was successfully performed without any
perioperative complications. The pathological findings were compatible with congenital bronchial atresia.
This is the first report of bronchial atresia in an accessory lobe. We must keep this lesson in mind because
such cases can suddenly develop serious complications.Keywords: Pneumothorax,  congenital bronchial atresia posterior, pulmonary lobe, accessory fissure
