脑后部可逆性脑病综合征的研究进展

Research Progress in Posterior Reversible Encephalopathy Syndrome

脑后部可逆性脑病综合征(PRES)是一种临床和影像学结合诊断的综合征。PRES病理机制尚不明确,以头痛、癫痫、精神状态改变、视力异常等为主要临床表现,以脑后部血管源性水肿为典型影像学表现,及时恰当治疗后临床和影像学异常能完全恢复。

The term of posterior reversible encephalopathy syndrome（PRES） refers to a clinicoradiological entity characterized by headache,epilepsy,mental status changes and visual abnormalities,and the radiological picture is typically associated with potentially vasogenic edema predominantly in the posterior regions of the brain,but the pathogenetic mechanism of this entity is poorly understood.Prompt and appropriate treatment leads to rapid reversal of the neurological and radiological abnormalities.
