Bronchiectasis is described in two persons following ammonia burns of the respiratory tract. The victims were exposed to anhydrous ammonia fumes for a period of 30 to 90 minutes respectively following a railroad tank-car derailment. Significant bronchiectatic changes were observed even though the admission chest roentgenogram was interpreted as normal in one case and as having an infiltration involving the lingula and left lower lobe present on the other. Follow-up radiographic studies should include a bronchogram when a person exposed to a corrosive gas remains symptomatic and inflammatory changes were present on the chest roentgenogram taken shortly after the incident.
