目的：探究可逆性后部脑病综合征（RPES）的影像学和临床表现。方法入选我院符合标准的患者54例，均给予MRI扫描，分析患者的影像学检查和临床表现特点。结果患者临床常见的症状主要为意识障碍、头痛、视觉障碍、恶心、发作性癫痫等，发病时常伴随血压升高，影像学表现为病灶主要分布在双侧大脑的后部皮层下白质区，经常可累及额叶、颞叶、脑干、小脑等。CT检查表现出低密度影，MRI检查表现出T1或长T2信号，18例行增强MR扫描后，16例无强化，2例患者出现不同程度的增强；MRA检查没有发现血管的异常，1例患者表现大脑双侧中动脉的走形僵直。患者经临床治疗后例39病症完全消失，10例病变明显的缩小，5例遗留坏死的软化改变。结论可逆性后部脑病综合征患者采用MRI检查，详细准确的显示出患者的病灶部位，影像学和临床表现具有一定的特点，有利于临床上正确诊断和治疗疾病，特点显著，值得推广。
目的：探究可逆性後部腦病綜閤徵（RPES）的影像學和臨床錶現。方法入選我院符閤標準的患者54例，均給予MRI掃描，分析患者的影像學檢查和臨床錶現特點。結果患者臨床常見的癥狀主要為意識障礙、頭痛、視覺障礙、噁心、髮作性癲癇等，髮病時常伴隨血壓升高，影像學錶現為病竈主要分佈在雙側大腦的後部皮層下白質區，經常可纍及額葉、顳葉、腦榦、小腦等。CT檢查錶現齣低密度影，MRI檢查錶現齣T1或長T2信號，18例行增彊MR掃描後，16例無彊化，2例患者齣現不同程度的增彊；MRA檢查沒有髮現血管的異常，1例患者錶現大腦雙側中動脈的走形僵直。患者經臨床治療後例39病癥完全消失，10例病變明顯的縮小，5例遺留壞死的軟化改變。結論可逆性後部腦病綜閤徵患者採用MRI檢查，詳細準確的顯示齣患者的病竈部位，影像學和臨床錶現具有一定的特點，有利于臨床上正確診斷和治療疾病，特點顯著，值得推廣。

Objective:To explore the clinical and imaging features of posterior reversible encephalopathy syndrome (PRES).Method:54 patients met the standard in our hospital were given MRI scanning, analysis of the patient's imaging characteristics and clinical manifestations.Result:The common clinical symptoms of patients were disturbance of consciousness, headache, visual disorder, nausea, epilepsy and so on.Morbidity associated with elevated blood pressure.Imaging showed focus was mainly distributed in the posterior subcortical white matter regions of both hemispheres of the brain like frontal lobe, temporal lobe, cerebel um, brainstem and so on.CT showed low density, MRI showed T1 and long T2 signal.After enhanced MRI scans in 18 cases, 16 cases showed no enhancement, 2 patients had different enhancement.MRA examination found no vascular anomalies, 1 patients showed the middle cerebral artery of bilateral cerebral deformation rigidity.Patients after clinical treatment, symptoms disappeared completely in 39, 10 cases of lesions reduced significantly, 5 cases left necrosis softening change.Conclusion:PRES treated by MRI examination show lesions detailed and accurate.Beneficial to the clinical diagnosis and treatment of disease.The curative effect is remarkable, is worth promoting the application.
