Background

The Larynx is a tube of squamous epithelium mucosa, with a cartilaginous skeleton and connecting ligaments, together with intrinsic muscles of the larynx surrounded by fatty spaces, and responsible for phonation and protection of the airway. It is located in the anterior portion of the neck and superior to the trachea. (1)

There are multiple pathologies that affect the larynx, from infectious, traumatic to tumorous, and therefore, it is the radiologist's duty to be familiar with them in order to be a crucial part of the multidisciplinary approach to laryngeal pathology.
