The visual cortex,the cerebellar vermis and hemispheres,and the postcentral cortex were significantly atrophic.The visual cortex was slightly hypointense on T1-weighted images and hyperintense on T2-weighted images.Probably representing the pathologic changes of status spongiosus. MR demonstrated the lesions,located in the calcarine area,cerebellum,and postcentral gyri,which are probably related to three of the characteristic manifestations of this disease:the constriction of the visual fields, ataxia,and sensory disturbance,respectively. |
