单纯局限性对称性双侧额顶部硬膜下间隙增宽成因分析

Only Symmetrical Bilateral Frontal and Parietal Subdural Space Broadening Genesis

目的:分析单纯局限性对称性双侧额顶部硬膜下间隙增宽的成因,提高对该影像表现的认识。方法:收集单纯局限性对称性双侧额顶部硬膜下间隙增宽的患者MRI影像39例(成人36例,婴儿3例),全面回顾患者的临床资料并跟踪随访。结果:36例成人患者中32例(以中青年居多)随访观察无变化(89.0%),3例婴儿随访观察全部恢复正常(100%)。结论:生理性脑退变、重力、婴幼儿时期的个体差异可能参与造成单纯局限性对称性双侧额顶部硬膜下间隙增宽。

Objective： To discuss the causes of only symmetrical bilateral frontal and parietal subdural space broadening.genesis.Method： 39 cases（36 cases in adults, baby 3）only limited amount of symmetrical bilateral subdural space at the frontal and parietal subdural space broadening of MRI imaging of patients were collected, comprehensive review of patient clinical data and follow-up.Result： Follow-up observation of 32 eases（Most young） and no change in 36 cases of adult patients（89.0%）, 3 cases of baby follow-up all return to norrnal（100%）.Conclusion： Physiological brain degeneration, Gravity, Individual differences in infant period can be involved in causing only symmetrical bilateral frontal and parietal subdural space broadening.
