CTICasesPost-intubation tracheal stenosis
Imaging findings
Lateral chest radiograph and neck CT show a focal, irregular, nodular narrowing of the mid-trachea causing severe airway stenosis, which developed three weeks after a short ICU stay requiring mechanical ventilation. Bronchoscopy confirmed a subglottic tracheal granuloma and stenosis.
Key takeaways
Tracheal stenosis is a well-documented complication of endotracheal intubation, usually caused by cuff-induced pressure necrosis leading to mucosal ischemia. It can present relatively rapidly post-extubation as localized granulation tissue or fibrotic stenosis.
