Background
A number of diseases affect central airway which may result in imaging abnormalities of the tracheal wall and lumen. Familiarity with radiological manifestations of these conditions is important. Our goal is to review, concisely yet comprehensively, pathological entities involving the central airway with the help of illustrative computed tomography (CT) images of selected diseases.

Educational Goals / Teaching Points
Brief review and clinical cases illustrating classical CT findings of the following entities will be provided including tracheomalacia, granulomatosis with polyangiitis, amyloidosis, sarcoidosis, relapsing polychondritis, inflammatory bowel disease, sarcoidosis, Keutel syndrome, Morquio syndrome, Mounier-Kuhn syndrome, tracheal papillomatosis, caustic injury, salivary gland tumors, foreign body aspiration, and rare anatomical variants.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
We will provide a concise review and examples of radiological manifestations of various congenital, inflammatory, metabolic, neoplastic and idiopathic conditions involving the trachea.

Conclusion
Radiologists should be familiar with pathological conditions affecting central airway.
