Imaging findings
Initial chest CT demonstrates necrotic mucosal debris and sloughing within the tracheal lumen at the thoracic inlet level. Follow-up chest CT obtained six weeks later reveals severe focal tracheal stenosis with circumferential soft-tissue thickening and granulation tissue narrowing the lumen.
Key takeaways
Post-intubation tracheal stenosis is a known iatrogenic complication arising from excessive endotracheal tube cuff pressure, leading to mucosal ischemia, necrosis, and subsequent cicatricial scarring. Symptoms and severe luminal narrowing can progress rapidly within weeks of extubation, requiring resection or endoscopic balloon dilatation.
