case_images: Preoperative computed tomography and intraoperative dynamic bronchoscopic images of the central airway. Preoperative transverse sectional computed tomography images of the (a) middle and (d) lower trachea during inspiration. Intraoperative bronchoscopic images of the (b) middle and (e) and lower trachea during inspiration under mechanical ventilation. Intraoperative bronchoscopy showing diffuse granular protrusions on the posterior wall of the (c) middle and (f) lower trachea during expiration under mechanical ventilation.

case_images: The admission CT scan showed no airway abnormalities (Figure 1(a), (d)), and he was scheduled for a bronchoscopic biopsy under general anesthesia. Bronchoscopic evaluation revealed that the posterior wall of the middle and lower trachea and both mainstem bronchi was raised, showing diffuse granular protrusions during both the inspiratory (Figure 1(b), (e)) and expiratory (Figure 1(c), (f)) phases of mechanical ventilation.

case_images: Complete tracheal collapse observed via bronchoscopy after endotracheal intubation. (a, b) Collapse near the front of the tracheal tube tip and (c, d) Collapse in the middle trachea.

case_images: Bronchoscopy revealed anterior bulging of the posterior membrane, with the tracheal lumen almost entirely collapsed (Figure 2).
