目的:分析中枢神经系统病毒感染临床特点。方法:对32例中枢神经系统病毒感染患者临床表现,脑脊液,头颅核磁,脑电图相关辅助检查进行分析。结果:中枢神经系统病毒感染患者起病形式复杂多样,多急性起病以头痛,发热最为常见。辅助检查中脑脊液异常率明显高于脑电图,头颅核磁。结论:以头痛,发热急性起病患者要考虑中枢神经系统感染可能性,脑脊液常规检查可做为中枢神经系统病毒性感染首选检查。 Objective: To analyze the clinical features of central nervous system virus infection. Methods: The clinical manifestations, cerebrospinal fluid (CSF), cranial magnetic resonance imaging and electroencephalography (EEG) related examination in 32 patients with central nervous system virus infection were analyzed. Results: The onset of CNS virus infection was complex and diverse. More acute onset was headache and fever was the most common. Auxiliary examination of cerebrospinal fluid abnormalities was significantly higher than the EEG, head MRI. Conclusion: Patients with acute onset of headache and fever should consider the possibility of CNS infection. Cerebrospinal fluid routine examination can be used as the first choice of detection of central nervous system viral infection.
