Question of high thyroglossal duct cyst on CT. Soft ballotable lesion behind frenulum at root of tongue, non painful. There is no significant narrowing of the trachea or discernible pyramidal lobe. There is globular enhancing tissue in the midline of the posterior root of the tongue that measures up to 15 mm. The thyroid is diffusely enlarged and contains nodules. The left lobe of the thyroid extends inferiorly to the level of the manubrium. There is no evidence of significant cervical lymphadenopathy based on size criteria. The salivary glands are unremarkable. The major cervical flow voids are grossly intact. The imaged orbits and intracranial structures are unremarkable. There is a retention cyst in the left maxillary sinus.
Findings compatible with ectopic lingual thyroid and a multinodular goiter.
