Imaging findings
Chest CT demonstrates diffuse, circumferential thickening of the entire tracheal wall, including the posterior membrane, extending down to the carina.
Key takeaways
Tracheobronchial amyloidosis typically presents with diffuse, circumferential thickening of the airway walls, distinguishing it from relapsing polychondritis (which usually spares the posterior membrane, except in acute inflammation). Laryngeal involvement is common. The diagnosis is confirmed by biopsy, and in many cases, the amyloidosis is confined to the airways without systemic manifestations.
