Abstract: Objective To explore the MRI diagnosis characteristics of reversible splenial lesion syndrome (RESLES).Methods The clinical and imaging data of 12 cases of RESLES was analyzed retrospectively.MRI plain scan and DWI of brain were performed in all the cases.Apparent diffusion coefficient (ADC) value was obtained through post-processing function.Results 8 of 12 cases were children and 4 were adults.The splenium of corpus callosum of 12 cases showed round lesions,with slightly long T1 and slightly long T2 signal on MRI,high signal on DWI,and low signal on ADC map.The mean value of ADC of 12 cases was about 0.43× 10-3 mm2/s.The MRI reexamination was made after treatment in 12 cases,which showed the lesion of splenium of corpus callosum disappeared,and clinical syndromes were improved.Conclusion The MRI manifestation of RESLES is characterized by solitary lesion.The ADC value could accurately reflect the molecular diffusion information of the lesion.
