Aspiration of foreign bodies into tracheobronchial tree is more common in children than adults, but can occur accidently during surgical and dental procedures. A 59 year old man was admitted for dry cough without dyspnea. In the past, that patient had been diagnosed as having schizophrenia and had been treated in the psychiatric clinic. A chest X-ray showed infiltration in left lower lung field. A high resolution computed tomography showed endobronchial tubular structure in distal left lower lobar bronchus and anterior basal segmental bronchi and irregular consolidation in the left lower lung. In operation room, elective flexible bronchoscopy was performed and the foreign body (vinyl) was removed.
