CTICasesIdiopathic Airway Calcifications
Imaging findings
CT chest shows extensive, idiopathic calcifications lining the walls of the distal lobar and segmental bronchi, with associated basal-predominant bronchial wall thickening and mild air trapping. The patient was a veteran with potential burn pit exposure.
Key takeaways
Tracheobronchial and distal airway calcifications can be idiopathic or related to chronic irritant exposure, such as dust, particulate matter, or smoking. Distinguishing these from other calcifying processes (like tracheobronchopathia osteoplastica) relies on checking wall involvement and clinical history.
