可逆性后部白质脑病综合征临床影像学特征

目的探讨可逆性后部白质脑病综合征(reversible posterior leukoencephalopathy syndrome,RPLS)的临床和影像学特点。方法回顾性分析8例可逆性后部白质脑病综合征患者的发病原因、临床症状、影像学特征、治疗及预后。结果8例患者中,女5例,男3例;发病原因多样,系统性红斑狼疮2例,妊娠子痫2例,高血压病1例,真菌性脑炎1例,多发性骨髓瘤1例,肾移植1例;其中使用免疫抑制剂3例,化疗药物1例,使用抗真菌药物1例。以头痛、癫痫发作、视觉障碍、意识和精神障碍为主要临床症状。多数患者头颅MRI表现为双侧大脑后部白质对称性T1WI呈低或等信号,T2WI和FLAIR像呈高信号;经采取降压、脱水及对症等治疗2~3周后患者神经系统症状消失,MRI复查病灶完全或大部分消失。结论RPLS是以可逆性后部白质损害为主要神经影像学表现的临床综合征,及时、准确的诊断和治疗可使其临床症状和影像学改变完全可逆。

Clinical and neuroimaging features of reversible posterior leukoencephalopathy syndrome

Objective To investigate the clinical and neuroimaging characteristics of patients with reversible posterior leukoencephalopathy syndrome(RPLS).Methods The etiology,clinical manifestations,neuroimaging features,treatment,and prognosis were retrospectively analyzed in 8 patients(5 males and 3 females)with RPLS.Results The causes of RPLS included systemic lupus erythematosus(2 cases)eclampsia(one case),primary hypertension(one case),fungal encephalitis(one case),multiple myeloma(one case),renal transplantatio...
