Laryngeal abnormalities are easily assessed clinically via direct visualization or endoscopically. Imaging may not be indicated in the setting of acute airway obstruction and diagnosis of common epithelial tumors such as squamous cell carcinoma is often made prior to imaging. However, non-acute laryngeal or other airway conditions often require radiological assessment because clinical pictures can be nonspecific and direct visualization or endoscopy cannot assess submucosal diseases very well. The purpose of this exhibit is to: 1. Review various non-acute 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. Endoscopic and radiological anatomy of the larynx and trachea 2. Non-acute laryngeal abnormalities a. Non-squamous cell neoplasms -Epithelial tumors -Non-epithelial tumors: granular cell tumor, rhabdomyoma, schwannoma, hemangioma, chondrosarcoma, lymphoma, metastasis, etc. b. Amyloidosis c. Laryngocele, laryngeal cyst d. Inflammatory / infectious conditions -Inflammatory: Granulomatosis with polyangitis, sarcoidosis, relapsing polychondritis -Infectious: Tuberculosis e. Post-traumatic abnormalities f. Post-treatment changes -Post-radiation changes -Post-surgical changes
