鄂西山区散发性病毒性脑炎脑电图头颅CT与临床分析

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

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 :6 0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 5 1例(85 .0 % ) ,正常 9例 (15 .0 % ) ;首次头颅CT异常 15例 (2 5 .0 % ) ,正常 4 5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 。

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.
