The patient is a 74-year-old man who had been showing worsening symptoms of the cough and sputum of which he had complained for years. He had smoked 20 cigarettes a day for more than 50 years. Because his chest roentgenogram revealed right middle lobe atelectasis, bronchoscopy was performed. Four tracheal diverticula were detected on the right membranous–cartilaginous portion of the subglottic trachea, with an additional 10 bronchial diverticula on the left main bronchus, and several diverticula on other sites of the bronchi. A large amount of purulent discharge was found in the entire visible area of the tracheobronchial lumen. Bronchial toilet ameliorated atelectasis. The case presented characteristics of acquired airway pulsion diverticula, and tracheal diverticula were detectable by chest roentgenogram. An underlying disease of chronic bronchitis may have contributed to the formation of airway diverticula.
