本文介绍1例功能自主性甲状腺结节反应异常的患者。其甲状腺结节不仅对放射性碘的摄取明显降低,而且在 TSH 刺激后结节完全消失。患者男性,44岁。物理检查发现右颈部有12.5×3厘米的孤立性块状物,位于甲状腺右下端,无触痛,可移动,未触及局部淋巴结。临床显示甲状腺机能正常。试验资料表明,T_3树脂摄取试验为48.4%(正常37～65%),T_4 9.2微克(正常3.8～12)。24小时摄碘率为25%(正常8～30%),扫描显示全部放射性浓集在结节内。连续三天每日肌注10单位 TSH 后,24小时摄碘
This article describes a case of functional autonomic thyroid nodules in patients with abnormal response. The thyroid nodules not only significantly reduce the uptake of radioactive iodine, nodules completely disappeared after TSH stimulation. Male patient, 44 years old. Physical examination found that the right neck 12.5 × 3 cm isolated lumps, located in the lower right thyroid, no tenderness, removable, without touching the local lymph nodes. Clinical thyroid function is normal. Test data show that T_3 resin uptake test was 48.4% (normal 37 ~ 65%), T_4 9.2 micrograms (normal 3.8 ~ 12). 24-hour rate of iodine uptake of 25% (normal 8 to 30%), the scan showed all the radioactive concentration in the nodules. After three days of daily intramuscular injection of 10 units of TSH, 24 hours of iodine uptake
