鄂西山区散发性病毒性脑炎脑电图头颅CT与临床分析

目的：对鄂西山区散发性病毒性脑炎的脑电图（EEG），头颅CT与临床进行分析，以提高诊断率，方法：60例临床确诊为散发性病毒性脑炎患者同时采用EEG及头颅CT检查。结果：首次EEG异常51例（85．0％），正常9例（15．0％）；首次头颅CT异常15例（25．0％），正常45例（75．0％）。经治疗3－4周后EEG异常的患者中33例再次复查，均有明显改善；CT异常的患者中2例重症脑炎再次复查，无明显改善。结论：头颅CT对散发性病毒性脑炎的诊断率不高，而EEG则与病情有较好的平行关系，建议在诊断散发性病毒性脑炎及判断其疗效时应首选EEG检查。

Clinical Analysis on Electroencephalogram and Cranial CT of Sporadic Viral Cerebritis in E'xi Area

Objective: To analyze the electroencephalogram (EEG) and cranial CT of the patients with sporadic viral cerebritis clinically.Methods: Sixty patients clinically confirmed with sporadic viral cerebritis underwent the examination of EEG and cranial CT simultaneously. Results: The abnormal findings of initial EEG were found in 51 cases (85%) and normal in 9 (15%); The abnormal findings of initial cranial CT were found in 15 cases(25%) and normal in 45(75%). After treatment for 3 to 4 weeks, 33 cases out of the 51 with abnormal EEG showed obvious improvement of EEG findings, while 2 cases of severe cerebritis from 15 with abnormal CT had no significant improvement of CT fingings. Conclusion: EEG had a good relation with the diseased condition. It was recommended to firstly choose EEG examination in the diagnosis of sporadic viral cerebritis.
