Abnormalities in the embryologic development and migration of the thyroid gland can result in ectopic thyroid tissue, which may occur on the midline in any position from the base of the tongue to the mediastinum. Although ectopic thyroid tissue may be asymptomatic, local obstructive, hemorrhagic or other complications may occur. Radionuclide thyroid scan is confirmatory when the diagnosis is suspected. Hypothyroidism is common in lingual thyroid, and thyroid supplementation is generally required.
甲状腺胚胎发育和迁移异常可导致异位甲状腺组织，其可出现在从舌根至纵隔的中线上的任何位置。虽然异位甲状腺组织可能无症状，但可能会出现局部梗阻、出血或其他并发症。当怀疑诊断时，放射性核素甲状腺扫描可确诊。舌甲状腺常见甲状腺功能减退，一般需要补充甲状腺素。
