CTICasesPost-Operative Tracheal Granulation Tissue
Imaging findings
CT chest shows irregular, soft-tissue nodularity and wall thickening at the site of a previous tracheal resection and anastomosis (for adenoid cystic carcinoma), causing mild luminal narrowing.
Key takeaways
Granulation tissue formation is a common, benign complication at the suture line of a tracheal anastomosis. It can cause post-operative stridor or airway narrowing, mimicking tumor recurrence, and requires endoscopic biopsy and debridement.
