Introduction: Inhalation of foreign body (FB) into the airway is considered a serious problem in a pediatric patient. Children of less attention by parents at an early age are more vulnerable to inhalation of FB. A long-standing undiagnosed FB such as whistle in bronchus is very rare and lethal. Case Report: A 6-year-old boy was presenting with a mild dry cough for 2 months. He had no evidence of breathing difficulty. He developed occasional whistling sounds during sleep for 5 days. Result: The FB was confirmed by computed tomography (CT) scan of the thorax and was removed successfully by rigid bronchoscopy under general anaesthesia without any complications. Conclusion: The diagnosis of FB in the bronchus is often difficult because of lack of parental ignorance and the absence of clear history. FB inhalation is often associated with significant morbidity.
