作者测量原发性甲减和席汉氏综合征患者的蝶鞍容积,并与正常人对照。结果发现:甲减患者14例平均蝶鞍容积为1350mm~3(±358-2SD);席汉氏综合征患者14例为330mm~3(±168-2SD),仅4例在正常范围;正常对照组200例,男122例,女78例,年龄10～68岁,平均蝶鞍容积为534mm~3(±280-2SD)。作者指出,原发性甲减和席汉氏综合征患者的蝶鞍大小与正常人相比有显著差别(P<0.001)。推测鞍鞍容积的改变与垂体功能变化有关,甲减时,TSH分泌增加,分泌TSH的细胞增生,垂体肥大,使蝶
The authors measure the sella volume in patients with primary hypothyroidism and Sheath’s syndrome and compare them with normal controls. The results showed that the average sella volume in 14 patients with hypothyroidism was 1350mm ~ 3 (± 358-2SD), while those in Sheath’s syndrome were 330mm ~ 3 (± 168-2SD), with only 4 in the normal range. Normal Control group of 200 cases, 122 males and 78 females, aged 10 to 68 years, the average sella volume was 534mm ~ 3 (± 280-2SD). The authors note that the size of the sella in patients with primary hypothyroidism and Sheath’s syndrome is significantly different from that in normal subjects (P <0.001). It is speculated that changes in saddle volume and changes in pituitary function, hypothyroidism, increased TSH secretion, secretion of TSH cell hyperplasia, pituitary hypertrophy, the butterfly
