A 58-year-old woman with thyroid hemiagenesis associated with subacute thyroiditis is described. Physical examinations revealed a firm nodule with spontaneous pain and tenderness in the left thyroid lobe. A serum thyroid hormone levels were elevated and thyroid scintiscan with 99mTc pertechnetate showed an extremely low uptake, we made a diagnosis of subacute thyroiditis. A 201Tl thyroid scan demonstrated an enlarged left lobe and absence of the right lobe. Ultrasonography of the thyroid gland revealed an enlarged left lobe occupied mostly with a hypoechoic region. An incidental finding was absence of the right lobe. Two months later thyroid function returned to normal. A follow-up thyroid scintiscan revealed a normal left lobe but absent right lobe. The diagnosis of hemiagenesis was confirmed by CT scan. This appears to be the first case report of thyroid hemiagenesis associated with subacute thyroiditis.
本文描述了一名58岁患有与亚急性甲状腺炎相关的甲状腺半侧缺如的女性。体格检查发现左甲状腺叶有一个质地坚硬的结节，伴有自发疼痛和压痛。血清甲状腺激素水平升高，99m锝高锝酸盐甲状腺闪烁扫描显示摄取极低，我们诊断为亚急性甲状腺炎。201铊甲状腺扫描显示左叶增大，右叶缺如。甲状腺超声检查显示左叶增大，大部分为低回声区。偶然发现右叶缺如。两个月后甲状腺功能恢复正常。随访甲状腺闪烁扫描显示左叶正常，但右叶缺如。CT扫描证实了半侧缺如的诊断。这似乎是第一例与亚急性甲状腺炎相关的甲状腺半侧缺如的病例报告。
