A well defined hyperdense lesion centred upon the base of the tongue with enhancement after contrast administration. It shows a few hypodense nodules. It is seen abutting the epiglottis. The mass encroaches upon the oropharyngeal airway which is relatively narrowed. It is seen surrounded by prominent small arteries and veins (seen within the epiglottis and ary-epiglottic folds).
No evidence of other thyroid tissue at the anatomical site of the thyroid gland.
