Whistle in the bronchus

An 18-year-old male presented with 4 weeks' history of productive cough and fever that had started 1 day after alleged ingestion of a plastic whistle. Multiple courses of antibiotics had proved ineffective. Crepitation and a localized wheeze on right chest were observed on clinical examination. Chest radiograph showed a right-sided pneumonitis. Bronchoscopy revealed a grayish-black foreign body in the right bronchial tree, which was retrieved and found to be the 'lost whistle.' The patient improved dramatically following the procedure.
