目的探讨脑后部可逆性脑病综合征(posterior reversible encephalop-athy syndrome,PRES)的临床和影像学特征。方法回顾性分析我院确诊的14例PRES患者的临床和影像学资料。结果14例患者均急性起病,其中妊高症5例,孕晚期无明确病因2例，孕晚期合并肾病综合征1例，高血压肾病4例，高血压脑病2例。表现为血压显著升高的13例，头痛的10例，视觉障碍的5例，意识障碍和癫痫发作的均6例。 CT显示为双侧顶枕叶白质为主的低密度影，MRI显示为双侧顶枕区皮质及皮层下白质多发病灶，T1低信号，T2高信号，FLAIR高信号。经积极治疗1~2w后，合并肾病综合征1例患者和高血压肾病1例患者症状好转，其余患者症状基本消失。结论 PRES以血压升高、头痛、视觉异常、意识障碍、癫痫发作为主要临床表现，且具有特征性的影像学表现，经及时治疗预后良好。
目的探討腦後部可逆性腦病綜閤徵(posterior reversible encephalop-athy syndrome,PRES)的臨床和影像學特徵。方法迴顧性分析我院確診的14例PRES患者的臨床和影像學資料。結果14例患者均急性起病,其中妊高癥5例,孕晚期無明確病因2例，孕晚期閤併腎病綜閤徵1例，高血壓腎病4例，高血壓腦病2例。錶現為血壓顯著升高的13例，頭痛的10例，視覺障礙的5例，意識障礙和癲癇髮作的均6例。 CT顯示為雙側頂枕葉白質為主的低密度影，MRI顯示為雙側頂枕區皮質及皮層下白質多髮病竈，T1低信號，T2高信號，FLAIR高信號。經積極治療1~2w後，閤併腎病綜閤徵1例患者和高血壓腎病1例患者癥狀好轉，其餘患者癥狀基本消失。結論 PRES以血壓升高、頭痛、視覺異常、意識障礙、癲癇髮作為主要臨床錶現，且具有特徵性的影像學錶現，經及時治療預後良好。

Objective To investigate the clinical and imaging characteristics of posterior reversible encephalopathy syndrome (PRES).Methods The clinical and imaging data of 14 patients with PRES diagnosed in my hospital were analyzed retrospectively.Results Al the patients were acute onset,5 cases with pregnancy hypertension,2 cases in the third trimester but no clear cause,1 case in the third trimeste with nephrotic syndrome,4 cases with hypertensive nephropathy,2 cases with hypertensive encephalopathy.13 cases with blood pressure significantly elevation,10cases with headache,5cases with disturbance of vision,6 cases with confusion and 6 cases with epilepsy.CT demonstrated low density shade in bilateral parietal and occipital lobes white mat er priarily,MRI revealed multiple lesions which were located in bilateral parietal and occipital lobes,involving grey mat er and white mat er,presented hypointense onT1WI,hyperintense on T2WI and FLAIR images.After 1~2 weeks of active treatment,the symptoms improved and the lesions dwindled of the patients with nephrotic syndrome and hypertensive nephropathy.The other were cured.Conclusion The main clinical manifestation of PRES were blood pressure elevation,headache,disordered vision,The prognosis wil be good if the treatment is timely given.
