| 摘 要： | 目的：分析原发性低颅压综合征的MRI表现，以提高对该病的认识。方法回顾性分析7例经腰穿证实的低颅压综合征患者的临床和MRI资料，7例患者均行头部MRI检查，1例仅行平扫，6例同时行平扫加增强。结果7例患者均表现为硬脑膜弥漫性增厚。增强6例见硬脑膜连续、无结节状线样强化，软脑膜无强化。5例静脉窦及大静脉扩张；2例见硬膜下积液；3例见脑下垂和脑室缩小；2例见垂体外形饱满；1例见双侧额颞顶部硬膜下血肿，1例见上段颈椎脊膜连续线样强化。结论低颅压综合征具有特征性的MRI表现，结合典型的临床症状，有助于早期诊断。

| Abstract: | Objective To analyze the magnetic resonance imaging （ MRI ） appearances of spontaneous intracranial hypotension syndrome （ SIHS） ,in order to improve the understanding of this disease .Methods The clini-cal data of 7 patients with SIHS confirmed by lumbar puncture were retrospectively analyzed .MRI was performed in all cases,in which there were 6 cases with contrast-enhanced MRI.Results All of them showed diffusely thickening of dural.6 cases with brain contrast-enhanced MRI demonstrated linear ,non-nodular and diffusely dural enhancement . The dilation of sinus and great vein were observed in 5 cases,subdural hydroma in 2 cases,brain sagging in 3 cases, pituitary gland plumpness in 2 cases,subdural hematoma in 1 case and 1 case with linear spinal dural enhancement . Conclusion The MRI manifestations of SIHS are characteristic ,and it will be helpful for the diagnosis by combining clinical data. |
