摘　　要：目的：应用MRI探讨空蝶鞍的发生率及其与年龄、性别的相关性。方法：对连续4000例行头颅MRI检查且无梗阻性脑积水患者资料进行回顾性分析，年龄10～89岁，平均53岁。按性别及年龄进行分组，观察空蝶鞍的发生率并进行统计分析。结果：4000例中空蝶鞍233例，发生率为5.82%，10～19、20～29、30～39、40～49、50～59、60～69、70～79和80～89岁年龄组空蝶鞍的发生率依次为0（0/214）、0.92%（2/217）、3.22%（14/435）、5.70%（34/597）、6.34%（41/647）、7.24%（56/773）、7.67%（58/756）和7.76%（28/361）。男女空蝶鞍发生率分别为3.76%（74/1967）和7.82%（159/2033），差异有统计学意义（χ^2=30.024，P=0.000）。40～49、50～59、60～69、70～79、80～89岁年龄组空蝶鞍发生率女性均高于男性（均P〈0.05）。结论：空蝶鞍发生率随年龄增长而升高，且男性低于女性。根据空碟鞍典型MRI表现，结合临床不难作出诊断。Objective：To explore the incidence of empty sella using MRI and its correlation with age and gender. Methods：Brain MR images of 4 000 consecutive subjects （age range,10-89 years;mean age,53 years） without obstructive hydrocephalus were analyzed retrospectively. Incidence of empty sella in different sex and age groups were recorded and statistical analyzed. Results：Empty sella were found in 233 of 4 000 patients,the total incidence of empty sella was 5.83%. The incidence of empty sella for male and female were 3.76%（74/1967） and 7.82%（159/2 033） （χ2=30.024,P=0.000）,respectively. The incidence of empty sella for groups of age 10~19,20~29,30~39,40~49,50~59,60~69,70~79 and 80~89 was 0% （0/214）,0.92% （2/217）,3.22% （14/435）,5.70% （34/597）,6.34% （41/647）,7.24% （56/773）,7.67% （58/756） and 7.76% （28/361）,respectively. The incidence of empty sella was higer in females than in males in all groups except group of age 10~19. Conclusion：The to-tal incidence of empty sella was 5.83%,which increases with age. The incidence of empty sella is lower in males than in fe-males.
