Imaging findings
Non-contrast chest CT and coronal reformats demonstrate an endobronchial calcified focus (broncholith) within a segment of the bronchial tree, associated with distal atelectasis and localized bronchial obstruction.
Key takeaways
Broncholithiasis typically arises when a calcified peribronchial lymph node, most commonly from a remote granulomatous infection such as histoplasmosis or tuberculosis, erodes through the bronchial wall into the airway lumen. This can cause partial or complete airway obstruction, leading to recurrent post-obstructive pneumonia, atelectasis, or hemoptysis.
