CTICasesIdiopathic Bronchial Calcification
Imaging findings
CT chest shows extensive, symmetric calcification outlining the walls of the segmental and subsegmental bronchi in both lungs, in an adult patient with mild asthma, without tracheobronchial stenosis.
Key takeaways
Exuberant bronchial wall calcification can occasionally be found as a benign, idiopathic, incidental finding. It must be differentiated from tracheobronchopathia osteoplastica (which spares the posterior membranous wall) or relapsing polychondritis (which typically causes stenosis and clinical symptoms).
