Results MRI of all WE patients showed symmetrical high signals on the brain T2WI, Flair and diffusion weighted imaging, 6 cases of them in the medial thalamus, 4 cases in surrounding the aqueduct, 3 cases in the third ventricle gray matter, 2 cases in the mamillary bodies, 1 case in the putamen,1 case in the optic chiasm, 1 case in the superior cerebella vermis and 1 case in the subcortical white matter; 2 cases had reinforcement effect. 2 cases showed no abnormal signals on T2WI and Flair early, but showed high signal symmetrically in the medial thalamus on DWI imaging.
