摘要：
Objective To observe the clinical characteristics, cerebrospinal fluid and imaging changes of primary intracra-nial hypotension syndrome. Methods Convenient selection in our hospital March 2013 to March 2016 admissions March primary of intracranial pressure syndrome patients in 22 cases, their clinical data were retrospectively analyzed. Results The primary hypointracranial compression syndrome prone age 30 to 45 years old, main clinical symptoms of orthostatic headache, dizziness, vomiting, tinnitus, some patients accompanied with different degrees of neurological signs, CSF pres-sure < 70 mmH2O, 8 patients with red blood cells increased, 9 cases patients CSF protein was elevated in, by imaging sci-ence examination can be seen in patients with dural enhancement, thickening, subdural visible seroma and hematoma, local tissue displacement, basal cistern stenosis, patients were given rehydration and symptomatic treatment, treatment effect is remarkable. Conclusion Primary low cranial orthostatic headache, cerebrospinal fluid pressure is low, the patients with ra-diologically visible dural enhancement, thickening, subdural visible seroma and hematoma, local tissue displacement, basal cistern stenosis change pressure syndrome are the main clinical characteristics.%目的：分析原发性低颅压综合征临床特征、脑脊液和影像学改变。方法方便选取该院2013年3月—2016年3月接诊的原发性低颅压综合征患者22例,对其临床资料进行回顾性分析。结果原发性低颅压综合征易发年龄为30~45岁,主要临床症状为体位性头痛、头晕、呕吐、耳鸣,部分患者伴有不同程度的神经系统体征,腰穿脑脊液压力﹤70 mmH2O,8例患者红细胞增多,9例患者脑脊液蛋白升高,经影像学检查可见患者硬膜强化、增厚,硬膜下可见积液及血肿,局部组织移位,基底池狭窄,给予患者补液及对症治疗,治疗效果显著。结论原发性低颅压综合征的主要临床特点为体位性头痛、腰穿脑脊液压力低,患者影像学可见硬膜强化、增厚,硬膜下可见积液及血肿,局部组织移位,基底池狭窄等改变。
