A Chest X-ray at the time of transfer to our hospital. The mediastinum was shifted to the right, and the airway from the upper trachea to the left main bronchus was steeply curved. B Bronchoscopic findings and schema of the trachea and the left bronchus. At the proximal side of the left main bronchus, the airway was barely patent during inspiration but was closed during expiration, which was caused by bronchomalacia. At the distal side of the left main bronchus, bronchial stenosis due to granuloma was revealed, but the secondary carina was intact
