Lingual thyroid is a rare developmental abnormality characterized by the failure of the thyroid gland, or remnants, to descend from anywhere along its embryologic path of origin at the foramen cecum to its normal eutopic pretracheal position. Awareness of the anatomic course of the embryologic thyroid primordium and typical and atypical locations of ectopic thyroid tissue may aid in diagnosis. The reported incidence of lingual thyroid is 1 in 100,000, and it is more common in females, with a female:male ratio ranging between 3:1 and 7:1. Lingual thyroid located at the base of tongue often present with hypothyroidism, usually asymptomatic but may cause dysphonia, dysphagia, upper airway obstruction, and hemorrhage. In the current case report, we present the imaging characteristics of lingual thyroid occurring in a 12-year-old female patient. Partial endoscopic removal of lingual thyroid was performed, followed by substitutive exogenous thyroid hormone therapy. The purpose of this article is to discuss the radiological characteristics and therapeutic issues in the management of lingual thyroid.
