The occurrence of ectopic lingual thyroid tissue was first reported over 100 years ago. We report an unusual presentation of ectopic thyroid tissue occurring in the submental area. A 27-year-old female presented to the Sultan Qaboos University Hospital in Muscat, Oman, in October 2011 with an 8 × 6 cm mass which caused difficulty in talking and a feeling of heaviness in the jaw. She was clinically and biochemically euthyroid upon presentation. The clinical diagnosis was confirmed by a technetium(-99m) thyroid scan, magnetic resonance imaging and fine needle aspiration. A single dose of 976 megabecquerels of radioactive iodine-131 resulted in hypothyroidism after three months and the complete disappearance of the swelling and associated symptoms. At a two-year follow-up, the patient was healthy and continuing lifelong replacement therapy with thyroxine.
异位舌甲状腺组织的出现早在100多年前就有报道。我们报告了一例发生在颏下区域的异位甲状腺组织的不寻常表现。一名27岁女性于2011年10月就诊于阿曼马斯喀特的苏丹卡布斯大学医院，其有一个8×6厘米的肿块，导致说话困难和颌部沉重感。就诊时她临床和生化检查甲状腺功能正常。通过锝（-99m）甲状腺扫描、磁共振成像和细针穿刺确诊了临床诊断。单剂量976兆贝可的放射性碘-131在三个月后导致甲状腺功能减退，肿胀及相关症状完全消失。在两年的随访中，患者健康，继续接受终身甲状腺素替代治疗。
