Silent thyroiditis and subacute thyroiditis are important causes of transient thyrotoxicosis from rapidly progressive tissue injury, followed by the release of thyroid hormone into the circulation. The most striking differences between them are severe pain and extreme tenderness in the thyroid region. Although the etiology of these diseases is not clarified, silent thyroiditis is basically occurred in autoimmune thyroiditis. The most difficult differential diagnosis of silent thyroiditis is Graves' disease. TSH receptor antibody (TRAb) is useful, but TRAb is rarely positive in silent thyroiditis. A low thyroid radioiodine uptake value is most useful in identified silent thyroiditis.
寂静性甲状腺炎和亚急性甲状腺炎是快速进行性组织损伤导致短暂甲状腺毒症的重要原因，随后甲状腺激素释放进入血液循环。它们之间最显著的区别是甲状腺区域的严重疼痛和极度压痛。尽管这些疾病的病因尚未明确，但寂静性甲状腺炎基本上发生于自身免疫性甲状腺炎。寂静性甲状腺炎最难鉴别的是格雷夫斯病。促甲状腺激素受体抗体（TRAb）很有用，但在寂静性甲状腺炎中TRAb很少呈阳性。甲状腺放射性碘摄取值低对诊断寂静性甲状腺炎最有用。
