Imaging findings
On inspiration, the trachea exhibits an abnormal, crescent-shaped contour described as a 'lunate trachea'. During expiration, the tracheal narrowing significantly worsens, appearing very severe.
Key takeaways
The presence of a 'lunate trachea' appearance on inspiratory imaging is a strong indicator of tracheobronchomalacia. Expiratory imaging is crucial for confirming the diagnosis by demonstrating excessive collapse or narrowing of the trachea.
