CTICasesBronchial atresia
Imaging findings
Chest CT and 3D color density reconstructions in a trauma patient demonstrate a localized area of hyperlucency and air trapping in the left upper lobe apex, associated with a dilated central bronchus that terminates blindly without connecting to the proximal bronchial tree.
Key takeaways
Bronchial atresia is a congenital abnormality characterized by focal narrowing or obliteration of a segmental or subsegmental bronchus. It typically presents as a localized area of hyperlucency and air trapping with a central mucous impaction (bronchocele), though the mucus plug may occasionally be absent.
