Abstract

BACKGROUND AND PURPOSE

To determine the frequency of serious intracranial abnormalities in a healthy young male population.

METHODS

Cranial MRI of 2,536 healthy young males, mean age 20.5 years, all applicants for military flying duties in the German Air Force.

RESULTS

The authors report a variety of morphological abnormalities in the brains of a large population of healthy young males, providing data on disease prevalence. Arachnoid cysts were found in 1.7% (95% CI 1.2 to 2.3%), vascular abnormalities in 0.51% (95% CI 0.29 to 0.9%), and intracranial tumors in 0.47% (95% CI 0.26 to 0.85%) of the applicants. No cerebral aneurysms were found.

CONCLUSION

The prevalence of primary brain tumors seems to be higher, whereas the prevalence of intracranial aneurysms is lower than expected. Only a small percentage of the detected abnormalities require urgent medical attention.

摘要

背景与目的

确定健康年轻男性人群中严重颅内异常的发生率。

方法

对2536名健康年轻男性进行头颅MRI检查，这些男性均为德国空军军事飞行任务的申请者，平均年龄20.5岁。

结果

作者报告了大量健康年轻男性大脑中存在多种形态学异常，提供了疾病患病率的数据。在申请者中，蛛网膜囊肿的发现率为1.7%（95%可信区间1.2%至2.3%），血管异常的发现率为0.51%（95%可信区间0.29%至0.9%），颅内肿瘤的发现率为0.47%（95%可信区间0.26%至0.85%）。未发现脑动脉瘤。
