"On imaging, these lesions are generally characterised as well-defined, thin-walled, fluid or air-filled cystic lesions in the paraglottic space. Communication with the laryngeal ventricle is not always identified, and an extralaryngeal extension through the thyrohyoid membrane may or may not be present."
"Typically seen as a well-defined, air or fluid-filled lesion related to the paraglottic space which has continuity with the laryngeal ventricle. The extent will depend on the subtype."
"internal (or simple): the dilated ventricular saccule is confined to the paralaryngeal space; it is contained by the thyrohyoid membrane (~40%)"
"T1 C+ (Gd): absent-to-minimal linear peripheral enhancement; when thick enhancing walls are present, consider pyolaryngocele"
