Multidisciplinary assessment of tracheal stenosis located in intrathoracic area. Three-dimensional CT at day1 both in the deep expiratory (Figure 2-A) and inspiratory phases (Figure 2-B) clearly depicts the airtrapping only in the deep expiratory phase (Figure 2-A) in the right hemithorax compared with the left hemithorax. Coronal image of thoracic CT on the same day (Figure 2-C) demonstrates the 4-cm mass located along the trachea to the right main bronchus, which severely compresses the intrathoracic upper airway, resulting in narrowing to a 4-mm-diameter. Bronchoscopy performed on the day of admission after intubation (Figure 2-D) shows the protruding tumor in the right main bronchus with mucosal edema, which occupies the almost entire tracheal lumen.
