A 49-year-old man with a clinical diagnosis of Graves' disease was referred for a thyroid scan and radioactive ablation of the gland. Tc-99m pertechnetate scan revealed a diffuse toxic goiter and radiotracer concentration in the thyroglossal duct. He was given 10 mCi of I-131 orally as treatment of thyrotoxicosis. Repeat scanning of the anterior neck 2 days later revealed concentration of radioiodine in the diffusely enlarged gland and the thyroglossal duct as found on the Tc-99m pertechnetate scan, thus confirming the presence of functioning thyroid tissue in the thyroglossal duct.
一名临床诊断为格雷夫斯病的49岁男性被转诊进行甲状腺扫描及甲状腺放射性消融治疗。锝-99m高锝酸盐扫描显示弥漫性毒性甲状腺肿以及甲状舌管内有放射性示踪剂浓聚。给予其口服10毫居里的碘-131以治疗甲状腺毒症。两天后对颈部前方进行再次扫描，结果显示放射性碘在弥漫性肿大的甲状腺及甲状舌管内浓聚，如同在锝-99m高锝酸盐扫描中所见，从而证实甲状舌管内存在有功能的甲状腺组织。
