| Summary: | Developmental defects of the thyroid gland are sporadic. Typical developmental abnormalities include ectopic thyroid, hemiagenesis, as well as agenesis of the thyroid gland. In children, ectopic thyroid gland is usually associated with hypothyroidism. Herein, we report a case of a 3-year-old girl with underlying congenital hypothyroidism, who also had functioning ectopic thyroid tissue in the sublingual region, as discovered during Tc-99m thyroid scintigraphy. Ultrasonography of the neck revealed an atrophic thyroid gland. Given that the lingual thyroid was the only functioning thyroid gland, and that there was no upper airway obstruction, she was treated conservatively with thyroid hormone and close monitoring. © 2022, University of Toronto.
