摘要
目的:探讨EV71感染小儿手足口病合并脑炎的3.0T MRI表现特征,提高诊断水平。方法:回顾性分析8例EV71感染小儿手足口病合并脑炎的3.0T MRI表现。结果:5例病灶局限在脑桥和延髓交界部,1例病灶以脑桥和延髓交界为主向两侧延伸,1例病灶位于脑桥偏背侧,1例位于中脑。8例病变均呈略长T1、长T2斑片状信号,边界欠清,DWI呈高信号。结论:EV71感染小儿手足口病合并脑炎3.0T MRI表现主要为位于脑桥和延髓交界区斑片状信号,3.0T MRI能真实地显示其脑炎脑部受损情况,对临床治疗提供可靠的影像学依据。
Purpose：To improve the comprehension of 3.0TMR imaging features of hand-foot-mouth disease（HFMD） encephalitis infected by EV71.Methods： The 3.0TMRI findings of 8 cases of HFMD encephalitis infected by EV71 were retrospectively analyzed.Results： The lesions in 6 cases were located in the junction of the pons and medulla oblongata,of which 1 lesion extended bilaterally at the same time.The other two lesions were separately located in dorsal pons and midbrain.All lesions demonstrated patchy slight hypointensity on T1WI and slight hyperintensity on T2WI.These ill-circumscribed lesions showed hyperintensity on diffusion-weighted imaing.Conclusion： HFMD encephalitis infected by EV71 possesses certain 3.0TMR imaging characteristics,which can provide reliable imaging evidence for clinical diagnosis.
