A 32-yr-old woman presented to the anesthetic clinic for preoperative evaluation for excision of a lingual thyroid. The pink mass was seen in the midline at the base of tongue and partly covered with yellow slough (Panel A). Contrast computed tomography showed the well-defined homogenously enhancing mass (black arrow) at the base of tongue (Panels B and C). The mass was not encroaching on the epiglottis (white arrow), and there was no evidence of airway obstruction.
Lingual thyroid is a rare developmental anomaly and results from failure in descent of the thyroid gland from the foramen cecum to its normal prelaryngeal site.1  The prevalence is 1:100,000 to 1:300,000 with a female:male ratio of 4:1.1
