Abstract

Dual ectopic thyroid is very rare. We report a case of dual ectopic thyroid in the lingual and infrahyoid areas in a 20-year-old female patient with no thyroid gland in its normal anatomical location. On physical examination, there was a 7 × 5 cm anterior midline neck swelling just below the hyoid bone and a 2 × 2 cm mass in the base of the tongue. Triiodothyronine (T3), thyroxine (T4), and thyroid-stimulating hormone (TSH) levels were normal. A thyroid scan with technetium-99m sodium pertechnate confirmed dual ectopic thyroid with no iodine uptake in the normal anatomical location of the thyroid gland. The infrahyoid ectopic thyroid was surgically removed for cosmetic reasons, and the lingual thyroid, which was symptomatic, was left untouched. The importance of thyroid scanning in the evaluation of anterior midline neck swellings and treatment options are discussed.
