Chief ComplaintProgressive dyspnea. History of 2-month-admission in the ICU due to ARDS 8 months ago.

Diagnosis: Tracheal Stenosis due to Intubation Injury
Radiologic Findings: Sequential Axial images (2-mm thickness) show subglottic segmental narrowing in the trachea. Lateral and posterior wall of the trachea is diffusely thickened. The trachea is not clearly distinguished from the esophagus. Volume-rendered 3D images demonstrate subglottic segmental narrowing of the trachea.
Brief Review: Pathologic examination of biopsy specimen obtained from tracheal stenotic portion showed inflammation and fibrosis without malignant cells or granuloma. His dyspnea was relieved with steroid medication although tracheal stenosis was still visible on chest radiography. Post-intubation tracheal stenosis usually occurs at the site of the cuff or stoma, subglottic stenosis has been also reported.
