摘　　要：可逆性后部脑病综合征(PRES)是一种临床-放射学综合征,其发病与多种因素有关,具体发病机制尚不明确。临床表现以头痛、癫癎发作、视觉障碍、不同程度的意识障碍及精神异常为主;影像学表现多累及后部脑区,呈大致对称性、多灶性分布,但有多种不典型影像学表现。一般预后良好,病程可逆。对PRES研究现状与进展作一综述。Posterior reversible encephalopathy syndrome （PRES） is a clinic-neuroradiologic entity with several causes. The pathogenesis of PRES is incompletely understood. Its clinical syndrome typically involves headache, seizures, visual symptoms and altered mental status. Imaging frequently shows symmetrical and multifocal abnormalities in the posterior brain regions, but several atypical imaging features are commonly described as well. Generally, it is reversible and benign.
