We describe the clinical features and MRI findings of a patient with hypereosinophilia-induced encephalopathy associated with human T-cell lymphotropic virus type 1.
Initial diffusion-weighted images revealed hyperintense spots in the border zone, and the apparent diffusion coefficient of the lesions increased over a three-week follow-up period. MRI findings, particularly those of the diffusion-weighted images, are of diagnostic value and are helpful in terms of understanding the pathophysiology of this disease.
