摘要：目的    分析22例流行性乙型脑炎（乙脑）患者临床资料，总结乙脑的临床及影像学特征，丰富乙脑诊治经验。方法    收集2011年1月至2011年12月广州市妇女儿童医疗中心神经康复科住院的22例乙脑患儿临床资料，分析发病特征、临床体征、影像学特征。对病例资料采用描述性分析的统计学方法。结果    临床特征方面：22例乙脑患者除均表现出高热、意识障碍、惊厥、肢体瘫痪外，其中4例还表现出帕金森综合征的症状及体征。影像学方面：22例中21例表现出双侧丘脑受损，具有帕金森综合征表现的4例除双侧丘脑受累外，还有中脑大脑脚受损的影像学证据。结论    乙脑除病毒性脑炎常见临床表现外，部分病例表现出帕金森综合征症状及体征，丘脑及中脑受累是乙脑的特征性影像学改变。
