Acute and subacute causes of upper airway narrowing can have a nonspecific and varied presentation, ranging from vague neck pain and shortness of breath to more obvious signs such as stridor. Given the nonspecific clinical presentation, imaging studies may sometimes be obtained prior to endoscopic evaluation. Additionally, endoscopic examinations cannot assess submucosal or extra-laryngeal causes of upper airway narrowing, necessitating radiologic assessment. The purpose of this exhibit is to: 1. Review various acute and subacute pathologies that cause laryngeal and airway compromise 2. Provide a clinicoradiological correlation of various disorders 3. Review of key imaging findings to narrow the differential diagnosis

1. Radiological anatomy of the larynx and trachea 2. Acute and subacute laryngeal abnormalities a. Infectious / inflammatory conditions -Epiglottitis -Croup -Retropharyngeal abscess -Hypopharyngeal abscess -Submandibular abscess -Odontogenic infection / oral floor abscess -Thrombophlebitis b. Angioedema c. Trauma d. Iatrogenic: post-extubation tracheal stenosis e. Tumors: advanced head and neck cancer
