目的分析低颅压综合征的临床特点与MRI诊断价值。方法回顾性分析经腰穿测压证实的12例低颅压综合征患者的临床和MRI表现。结果本组12例低颅压综合征患者中均有特征性的体位性头痛,12例患者CSF压力<60mmH2O。MRI表现包括弥漫性硬脑膜强化12例;脑下垂5例;硬膜下积液4例;硬膜下血肿2例。结论低颅压综合征的MRI表现具有特征性,尤其是增强后硬脑膜弥漫强化征象对本病的诊断很有价值。
Objective To analyze the clinical characteristics and MRI diagnosis of intracranial hypotension syndrome. Methods The clinical and MRI findings of 12 patients with low intracranial pressure syndrome confirmed by lumbar puncture were retrospectively analyzed. Results All the 12 patients with low intracranial pressure syndrome had characteristic positional headache. The CSF pressure of 12 patients was less than 60 mmH2O. MRI manifestations include diffuse dura in 12 cases; 5 cases of ptosis; 4 cases of subdural effusion; 2 cases of subdural hematoma. Conclusion MRI manifestations of low intracranial pressure syndrome are characteristic, especially the enhanced signs of diffuse dura mater are valuable for the diagnosis of this disease.
