摘要 目的探讨妊娠高血压综合征(妊高征)的并发症—可逆性后部白质脑病综合征(RPLS)的影像学诊断和转归。方法在86例临床最后诊断为妊高征合并RPLS中,首次对其中68例行颅脑CT检查,45例行MRI检查,同时行CT及MRI检查者27例;于7d~1a内1~4次复查CT/MRI。回顾性分析全部首次和复查的颅脑CT/MRI表现。结果①86例RPLS中,轻度35例,中度41例,重度10例。②病灶分布:左枕顶叶77例,右枕顶叶82例,左额叶45例,右额叶50例,左颞叶14例,右颞叶11例,小脑7例,基底节区3例,脑干2例,丘脑2例。③复查(最后一次CT/MRI)所见,正常75例,CT/MRI留有低密度灶或异常信号11例。35例轻度者全部恢复正常,41例中度者6例留有异常,10例重度者5例留有异常。结论①妊高征并发RPLS以轻、中度为主。②RPLS病变主要分布于后循环供血区,常见双侧枕顶叶对称性的皮质下白质脑水肿,其次是额颞叶,小脑、基底节、脑干或丘脑可受累。③RPLS经过积极有效的治疗大多数病例影像学明显改善或完全恢复。少数留有不可逆脑局部损伤征象,以重度RPLS为主,造成不同程度的神经系统后遗症。
