A sizable right laryngeal cystic lesion with supra and infra-hyoid location (namely at the laryngeal supra-glottic region) with its inferior aspect reaching the level of the laryngeal ventricle. Laterally, the lesion is seen extending outside the laryngeal cartilaginous framework through the thyrohyoid membrane. The lesion displayed near water density with enhancing rim of uniform thickness.
The laryngeal component of the lesion is seen compressing the right aryepiglottic fold, pyriform sinus and extending anteriorly to the peri-epiglottic space, while the extra-laryngeal part is seen insinuating itself between the right submandibular gland (which is displaced anteriorly) and the ventral surface of the sternomastoid muscle.
