摘要
目的:分析14例低颅压综合征的临床特点及其MRI表现。方法:回顾性分析14例低颅压综合征患者的临床及MRI资料。结果:所有患者均有特征性体位性头痛;特征性MRI表现为7(7/8)例显示硬脑膜增厚,8(8/8)例显示窦汇扩张(后下缘后凸呈弧形),7(7/8)例显示双侧硬脑膜弥漫性对称性均匀性强化,10(10/14)例MRM示脊膜憩室、囊肿、脑脊液漏。结论:低颅压综合征的临床特点多样,体位性头痛是其特征性症状;头颅MRI增强扫描具有特征性表现,MRM可较为明确的显示脑脊液漏的部位;MRI检查在低颅压综合征的诊断中具有较大应用价值。
Objective：To investigate the clinical characteristics and MRI findings of intracranial hypotension syndrome.Methods：The clinical and MRI data in 14 cases of intracranial hypotension syndrome were analyzed retrospectively.Results：All the 14 cases appeared orthostatic headache.7（7/8） cases appeared cerebral dura mater uniform,diffuse and symmetrical thickening,8（8/8） cases appeared confluence of sinuses dilated（aft-inferior edge protruded astern）,7（7/8） cases manifested bilateral cerebral dura mater uniform,diffuse and symmetrical enhancement,10（10/14） cases MRM appeared spinal meninges diverticulum,cyst and leakage of cerebrospinal fluid.Conclusion：Intracranial hypotension syndrome typically presents with orthostatic headache,which is often associated with additional symptoms;enhanced MRI has markable appearances.MRM can display the location of the leakage of cerebrospinal fluid obviously.MRI has a significant diagnostic value on intracranial hypotension syndrome.
