| 目的 探讨先兆子痫(PE)后部可逆性脑病综合征(PRES)的MRI表现及其与横窦引流模式的关系。方法 回顾性分析45例PE患者临床及MRI资料,其中早发型21例(孕周<32周),晚发型24例(孕周≥32周),根据是否伴有PRES分为PRES组(n=21)和无PRES组(n=24)。观察两组中横窦的引流模式、PRES组中PRES的发生部位及信号特征,并进行统计学分析。结果 早发型PE患者中PRES发生率高于晚发型[66.67%(14/21)、29.17(7/24),χ2=6.19,P=0.02]。PRES组常规MRI均呈长T1长T2,T2WI/FLAIR呈高信号,DWI呈等信号,ADC图呈高信号。45例PE患者中横窦引流模式为单侧优势型34例,PRES发生率为55.88%(19/34),均衡型11例,PRES发生率为18.18%(2/11),差异有统计学意义(χ2=4.70,P=0.02)。结论 PE患者并发PRES的MRI表现具有一定特征性,单侧横窦引流模式与PRES的发生有密切关系。 |

| Objective To explore MRI manifestations of pre-eclampsia posterior reversible encephalopathy syndrome (PRES) and its association with transverse sinus drainage pattern.Methods Clinic and MRI datum of 45 pre-eclampsia (PE) patients were retrospectively reviewed,among which 21 cases were early onset (gestational weeks<32 weeks),24 cases were late onset (gestational weeks≥32 weeks).According to whether had PRES,all patients were divided into PRES group (n=21) and non-PRES group (n=24).Transverse sinuses drainage modal,part of PRES and signal features were observed,and statistic analysis was performed.Results The rate of PRES in early onset was higher than that in late onset (66.67% [14/21] vs 29.17% [7/24],χ2=6.19,P=0.02).PRES group were showed long T1 long T2 on conventional MRI,hyperintense on T2WI/FLAIR,isointense on DWI,and hyperintensity on ADC.There were 34 cases with unilateral transverse sinus drainage modal in 45 patients,and PRES occurrence rate was 55.88% (19/34);there were 11 cases with balanced drainage modal,and PRES occurrence rate was 18.18% (2/11);statistical difference was significant (χ2=4.70,P=0.02).Conclusion MRI manifestations of PRES has some characteristics,and unilateral transverse sinus drainage modal is closely related to PRES. |
