Abstract:
A 40-year-old male with Cystic Fibrosis developed a sudden onset choking, cough, dyspnea and hemoptysis after using his inhaler. He presented to A&E. CT scan located a foreign body in his right bronchus intermedius (RBI). Rigid bronchoscopy was performed and removed a plastic rawl plug with screw from his RBI. He made a rapid recovery. On questioning he mentioned he had stored his inhaler uncapped in the same pocket he had this screw which he found at work. Small objects can lodge in inhalers due to their design/mouthpiece uncapping. This can result in endobronchial foreign body aspiration. This case highlights the importance of replacing inhaler cap when not in use.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
