Axial lung window

Tubular, low density right upper lobe structure branching away from the hilum without connection to the tracheobronchial tree. The surrounding lung is hyperlucent due to air trapping.
Case Discussion
Findings are typical for bronchial atresia where there is no connection of a portion of the bronchial tree with the central airways, resulting in a build-up of secretions with dilation of the affected airway and air trapping in the surrounding lung.
