One case of reversible posterior encephalopathy syndrome and literature review
可逆性后部脑病综合征1例并文献综述

摘要

可逆性后部脑病综合征是一组临床影像学综合征，病因多种多样，大多合并较严重的基础疾病。PRES中最常见的神经影像学异常累及大脑后半球的皮质下白质，尤其是双侧顶叶和枕叶区域。PRES与双侧大脑后动脉梗死的区别是距状裂和枕叶中线旁结构通常保留。多数PRES患者的枕叶和顶叶均出现双侧水肿病变。本文报道一例癫痫发作后头痛伴视物模糊的患者，通过头颅MRI检查确诊PRES，经脱水、改善循环、对症等治疗后，患者预后较好，临床症状和影像学改变完全消失，从而增强临床医师对该病的认识。本文将该例患者诊疗经过进行总结，以期为相关病历作参考。

Abstract

Reversible posterior encephalopathy syndrome is a clinical imaging syndrome with various etiologies, mostly accompanied by more severe underlying diseases. The most common neuroimaging abnormalities in PRES involve subcortical white matter in the posterior hemisphere of the brain, especially in the bilateral parietal and occipital lobes. The difference between PRES and bilateral posterior cerebral artery infarction is that the structures adjacent to the midline of the occipital lobe and the spinous fissure are usually preserved. Most PRES patients have bilateral edema lesions in the occipital and parietal lobes. This article reports a patient with post-stroke pain and blurred vision who was diagnosed with Pres through cranial MRI examination. After dehydration, improvement of circulation, symptomatic treatment, etc., the patient's prognosis was good, and clinical symptoms and imaging changes completely disappeared, thereby enhancing clinical physicians' understanding of the disease. This article summarizes the diagnosis and treatment process of the patient in order to provide reference for relevant medical records.
