Imaging Findings
Differential Diagnosis
• Tracheobronchomalacia (TBM): Excessive airway collapsibility secondary to weakness of the airway wall is known as TBM.
• Tracheobronchial stenosis: A fundamental difference between tracheobronchial stenosis and several different pathologic conditions (amyloidosis, sarcoidosis, relapsing polychondritis) is the fixed nature of the airway narrowing.
