Diffusion-Weighted MRI in Recurrent Wernicke's Encephalopathy: a Remarkable Cerebellar Lesion

ABSTRACT

We report unusual MRI findings (including those from diffusion-weighted imaging (DWI)) in a patient with recurrent Wernicke's encephalopathy with a remarkable cerebellar lesion. DWI showed high signal intensities in the superior portion of the cerebellar hemisphere and vermis area. After thiamine administration, clinical symptoms improved and the lesions with high signal intensities disappeared on follow-up DWI.
