作者观察了原发性甲减患者12例在接受甲状腺素治疗前后垂体窝的 CT 检查结果。原发性甲减患者均为女性,平均年龄为39(16～69)岁。有甲减的临床表现;血清游离甲状腺素指数(FT_4I)减少或在正常低限(FT_4I 通过 T_3树脂摄取率与 T_4乘积来表示);血清促甲状腺索(TSH)水平增加。所有甲减均为自发性,其中11人由于自身免疫性甲状腺炎所致(血清抗甲状腺微粒体抗体>1:10~6)。在行甲状腺素治疗前摄蝶鞍平片并作无和有对比剂的蝶鞍 CT 检查。注射对比剂前,所有患者蝶鞍内容物的密度值均正常。3人有轻微的蝶隔疝故未能确定蝶鞍
The authors observed the CT findings of pituitary fossa in 12 patients with primary hypothyroidism before and after thyroxine treatment. Primary hypothyroidism patients were female, with an average age of 39 (16 to 69) years old. The clinical manifestations of hypothyroidism; serum free thyroxine index (FT_4I) decreased or at the lower limit of normal (FT_4I by T_3 resin uptake and T_4 product to represent); serum thyroid TSH levels increased. All hypothyroidism was spontaneous, of which 11 were due to autoimmune thyroiditis (serum anti-thyroid microsomal antibodies> 1: 10 ~ 6). In the line of thyroid hormone treatment of preoperative sellar plain film and without sella contrast CT sessile examination. Before injection of contrast agent, the contents of sella in all patients were normal. 3 people have a slight septal hernia and therefore failed to determine the sella
