Lingual thyroid is a rare developmental anomaly. It is the result of failure of the thyroid to descend from the foramen caecum to its prelaryngeal site. Lithium is a known goitrogen, but has never been reported to cause symptomatic enlargement of the lingual thyroid. We describe a 40-year-old woman, who presented with a foreign body sensation and progressive dysphagia caused by an ectopic lingual thyroid tissue measuring 4 cm x 3 cm x 3.5 cm. She had been taking lithium for treatment of bipolar disorder and had hypothyroidism. Her symptoms were relieved after excision of the ectopic thyroid tissue.
舌甲状腺是一种罕见的发育异常。它是甲状腺未能从盲孔下降至其喉前位置的结果。锂是一种已知的致甲状腺肿物质，但从未有过导致舌甲状腺出现症状性肿大的报道。我们描述了一名40岁女性，她因一块大小为4厘米×3厘米×3.5厘米的异位舌甲状腺组织而出现异物感和进行性吞咽困难。她一直在服用锂治疗双相情感障碍，并且患有甲状腺功能减退症。切除异位甲状腺组织后，她的症状得到了缓解。
