Abstract
- Ectopic thyroid is an uncommon status characterized by the presence of thyroid tissue in a site other than in its usual region. It is rare for dual ectopic thyroid to have two ectopic foci simultaneously. Three cases of dual ectopic thyroid have been reported in the Korean literature. Clinically, most cases in ectopic thyroid were noted at adolescence or postpartum due to increased physiologic hormonal demands. Clinical manifestation, thyroid function test, and radiologic imaging should be employed to make a diagnosis and therapeutic plan of this disease. We present a patient with dual ectopic thyroid tissue in the suprahyoid and infrahyoid area without thyroid tissue in its normal thyroid bed.
