摘要/Abstract

摘要： 脑室周围结节型异位(periventricular nodular heterotopia,PNH)是一种由神经元细胞迁移障碍引起的脑发育畸形病,表现为脑室周围存在结节状的异位灰质。PNH可能是由于相关基因的突变所致。在PNH的MRI图像上可以看见脑室周围存在结节状异位灰质,其信号强度与大脑皮质一致。功能磁共振等影像学技术也开始应用于PNH的研究,并取得了一定的成果。PNH最常见的临床症状为癫痫,因此如何确定致癫区和切断其癫痫样电活动传播是治疗的关键,脑电图(EEG)技术成为了诊断PNH相关癫痫的必不可少的方法,特别是立体定向脑电图(SEEG)技术的出现使得癫痫的诊疗方面有了极大地进步。PNH所致的难治性癫痫的的外科治疗包括传统切除手术、射频热凝治疗(radiofrequency thermal coagulation,RF-TC)和激光间质内热凝(laserinterstitial thermal therapy LITT),目前以RF-TC为主要的治疗方式。
