摘要
目的 :分析自发性低颅压综合征的临床特点和MRI表现。材料和方法 :5例SIH患者均行腰穿和MRI检查。结果 :5例患者均有特征性体位性头痛症状 ,腰穿脑脊液压力为 98～ 490Pa( 10～ 5 0mmH2 O) ,MRI平扫示 4例出现脑膜增厚 ,增强扫描显示双侧额、顶、颞、枕颅板下方及小脑幕脑膜对称性条状增强 ,1例出现硬膜下出血 ,2例出现脑下垂 ,保守治疗后出血吸收 ,脑下垂表现缓解。结论 :综合分析临床表现。
Purpose: To analysis the clinical characteristics and MRI findings of spontaneous intracranial hypotension syndrome. Materials and Methods: All the 5 cases of spontaneous intracranial hypotension had both lumber puncture and MRI examination. Results: Typitcal clinical symptom of postural headache and lower CSF pressure (10～50 mm H_2O) were seen in all the patients. Contrasted MRI delineated dura mater thickening of the bilateral cerebral and cerebellum tentorium appear as linear enhancement in 4 cases. 1 case accompanied with subdural haematoma and 2 cases with brain sagging. The subdural haematoma absorbed and brain sagging relieved after conservation managements. Conclusion: Compositive analysis of clinic presentations, CSF pressure and MRI findings can help to make diagnosis of spontaneous intracranial hypotension.
