NEJM:原发性甲状腺功能减退症垂体增生症-病例报道

2019-02-21 xing.T 网络

患者开始接受左旋甲状腺素治疗,由于通过下丘脑-垂体-甲状腺轴的激素反馈机制,长期未经治疗的原发性甲状腺功能减退症可引起垂体增生。

患者为一名10岁的女孩,因头痛和生长不良而到儿科就诊。在检查时,她的身高低于第三百分位,她的体重在第十百分位数。她皮肤干燥;眼科检查显示没有视野缺陷。

实验室检查发现促甲状腺激素水平超过150μU/ml(正常范围为0.5至4.9),游离甲状腺素水平为0.4 ng/dl(5.1 pmol/L)(正常范围为0.8至1.4 ng/dl[10.3-18.0 pmol/l]),催乳素水平为63 ng/ml(正常范围为3至28)。额外检查的结果是正常的,包括评估早晨皮质醇、促性腺激素和胰岛素样生长因子1的水平。头部的磁共振成像(MRI)显示在延伸到视交叉的鞍区域中的弥漫性增强病变(如图A箭头所示),诊断为原发性甲状腺功能减退伴继发性垂体增生。



患者开始接受左旋甲状腺素治疗,由于通过下丘脑-垂体-甲状腺轴的激素反馈机制,长期未经治疗的原发性甲状腺功能减退症可引起垂体增生。

在10个月的随访中,患者的头痛已经消退,促甲状腺激素水平正常化,患者身高增长6厘米。头部的重复MRI显示垂体增大消除(如图B所示)。
