摘要 【目的】分析脑灰质异位所致癫痫的临床表现与脑电图特点。【方法】对10例脑灰质异位(HGM)所致癫痫患者的临床发作特点、影像学资料、脑电图特点和抗癫痫药的治疗效果进行分析。【结果】本组于12岁前出现癫痫发作者有7例(70%);主要发作类型为全面强直-阵挛性发作,共8例(80%);头颅 MRI 检查发现多发性的不规则结节灶6例(60%),位于双额、顶叶白质内5例(50%);10例均有脑电图异常,其中6例(60%)异常放电的部位与病灶部位基本一致;药物有效6例,难治性癫痫4例。【结论】脑灰质异位所致癫痫发病年龄早,主要发作类型为全面强直-阵挛性发作,脑电图异常放电与病灶部位有一定的相关性,约半数的患者正规的药物治疗有效。
