Case of a fractured human bone fragment as an endobronchial foreign body following a traffic incident

Endobronchial foreign bodies (EFBs) are present in various settings, such as eating or dental procedure. Accidental aspiration of foreign bodies is more common in children; however, cases of adult foreign body aspiration exist. Traumatic incidents can precipitate endobronchial aspiration of foreign bodies. Loss of consciousness, such as in coma, can result in foreign bodies being easily inhaled into the airways. Teeth or vehicle parts have been reported as EFBs following traumatic incidents. We report on a patient with chronic, sustained cough following maxillofacial trauma. Chest CT revealed an abnormal calcified endobronchial opacity. Flexible bronchoscopy confirmed the presence of an endobronchial foreign body in the left main bronchus. Following removal by bronchial forceps, the body was identified as a human bone fragment. Successful removal of the endobronchial bone fragment resulted in complete symptom remission. We concluded that post-traumatic respiratory complaints should be comprehensively evaluated, even if mild.
