摘要
目的探讨原发性低颅压综合征(SIH)的MRI表现。资料与方法回顾分析8例经临床证实的SIH患者的临床和MRI资料。结果头颅MRI示硬膜下积液、硬脑膜增厚8例,静脉窦和脑静脉扩张7例,脑下垂2例,垂体增大1例。增强扫描6例均见硬膜均匀性增厚强化。2例脊髓MRI示蛛网膜下腔均匀变窄,硬脊膜外积液。腰穿结果提示8例患者脑脊液压力均<60 mm HO。结论 MRI能显示SIH的特征性表现,有助于临床诊断。
Objective To explore the Magnetic resonance imaging（MRI） findings of Spontaneous intracranial hypotension syndrom（SIHS）.Materials and Methods The clinical and imaging data of 8 patients with SIHS were retrosepectively analyzed.Results MRI findings included dural thickening and subdural fluid collection in 8 cases,cerebral veins dilated in 7 cases,brain descensus in 2 cases,and enlargement of pituitary gland in 1 cases.Contrast T1-weighted MR scan showed diffused endocranium thickening and enhancement in 6 cases.On spinal cord MRI,subarachnoid space showed narrow and epidural fluid collection in 2 cases.Eight patients had lower CSF pressure（60 mm H2O）.Conclu-sion MRI can reveal the characteristic findings of SIHS,which contribute to the clinical diagnosis.
