摘要
目的探讨原发性低颅压综合征(SIH)的临床特征及MRI表现,提高对本病的认识和诊断准确率。材料与方法回顾性分析22例确诊为SIH患者的临床及MRI资料,总结、分析SIH患者的临床表现及MRI特征。结果 22例SIH患者临床出现体位性头痛22例(100%)、水平侧卧位CSF压<60 mm H2O(100%),颈部强直10例,听力障碍8例;MRI检查硬脑膜弥漫均匀强化22例(100%),脑下垂20例,脑室减小10例,静脉窦扩张7例。结论体位性头痛和CSF压减低是SIH的重要临床特征,硬脑膜弥漫均匀强化与脑下垂是SIH的重要MRI表现,SIH的临床及MRI均具有特征性表现,增强MRI是影像诊断SIH的重要手段。
Objective:To investigate the clinical presentation and MRI characteristics of spontaneous intracranial hypotension (SIH) syndrome. Materials and Methods: Retrospective analysis of clinical presentation and MR imaging of 22 SIH patients, to summarize the characteristics of clinical presentation and MRI of (SIH). Results:Typical postural headache and the low CSF pressure (less than 60 mm H2O) ware found in the all patients. In the 22 patients, 10 cervical rigidity and 8 Hearing Disorders ware found. On MRI, all patients showed pachymeningeal diffuse enhancement, other findings included sagging brain (20), diminution of cerebral ventricles (10), enlargement of venous sinus (7). Conclusions:Postural headache and the low CSF pressure are the important clinical characteristics of SIH, diffuse enhancement of cerebral dura mater and sagging brain are the important MRI characteristics of SIH, enhanced MR was the important method in diagnosis of SIH.
