Imaging findings
Concentric narrowing with wall thickening and associated calcification in the proximal right mainstem bronchus, extending into the bronchus intermedius. Distal to the obstruction, there was post-obstructive atelectasis in the right lower lobe.
Key takeaways
Airway amyloidosis can present as concentric bronchial narrowing with wall thickening and calcification, leading to post-obstructive atelectasis. This case highlights the importance of considering amyloidosis in the differential for bronchial stenosis.
