Diagnosis: Adult lingual thyroglossal duct cyst (TGDC)

Thyroglossal duct cyst originates from the retention of an epithelial tract that is formed during the migration of the thyroid gland during embryogenesis. It commonly presents as a midline neck mass near the level of the hyoid bone and accounts for approximately 70% of congenital neck abnormalities.¹ The TGDCs are usually detected in childhood and are most frequently encountered in the anterior aspect of the neck; only 1% to 2% of TGDCs are found at the base of the tongue.² Most reports of lingual TGDCs have occurred in infants and children. In young infants, lingual TGDCs may lead to respiratory and feeding difficulties³ and even sudden death.⁴ The most common symptoms and signs of lingual TGDCs, including intermittent or continuous stridor, coarse breathing sounds, and accessory muscle retractions, are caused by upper airway obstruction. To the best our knowledge, no cases of lingual TGDC have been reported in adults.
