MRI manifestations of encephalitis in children with severe hand-foot-mouth disease

Objective：To investigate the MRI manifestations of encephalitis in children with severe hand-foot-mouth disease（HFMD）.Methods：Imaging materials of 24cases of encephalitis in children with SHFMD were analyzed retrospectively.Results：There were 69lesions in 24cases with children＇s SHFMD.Multiple lesions were presented in 13cases,including 10cases of symmetrical lesions and 3cases of asymmetricay lesions.Multiple lesions mostly involved white matter（n= 37）.11cases manifested single lesions which involved thalamencephalon（n=2）,basal ganglia（n=4）,brain stem （n=2）, lobus temporalis（n=1）,and frontal lobe（n=1）.The lesions were mostly patchy hyporntense/sligtly hypointense on T1WI and hyperintense/slightly hyperintense on T2WI,T2-FLAIR and DWI with blurred border,some lesions were shown clearly on T2-FLAIR or DWI.Conclusion：Characteristice features of encephalitis in children with SHFMD are shown on MRI and have high sensitivity in the diagnosis.MRI can show position,extent and severity in diagnosing encephalitis in children with SHFMD. 【
