目的 探讨锥体外系症状在病毒性脑炎中的发生率、临床特点及发病机制。方法 回顾分析436例临床确诊的病毒性脑炎患者的临床资料。结果 436例中 41例 (9 36 % ) )出现锥体外系症状 ,多数在病程第 1～ 2周内发生 ,少儿患者以扭转痉挛、舞蹈、手足徐动症多见 ,青壮年患者以震颤多见 ,出现锥体外系症状者不一定有相关影像学的改变 ,其预后较未合并锥体外系症状者差。结论 病毒性脑炎患者出现锥体外系症状可以作为判断病情严重性及预后的指标之一

Methods A retrospective analysis of 436 cases of clinically diagnosed patients with viral encephalitis clinical data. Results 41 cases (436%) of 436 cases had extrapyramidal symptoms, most of which occurred within 1-2 weeks of course of disease. Children with torsion spasm, dances, hand-foot-and-arm seizures were more common, young patients were more tremor See, extra-pyramidal symptoms are not necessarily related to imaging changes, the prognosis than those without extra-pyramidal symptoms were poor.
