Abstract

We report a 16-month-old boy with human herpes virus-6 (HHV-6) encephalopathy showing transient abnormalities of the cerebral white matter on magnetic resonance imaging. Diffusion-weighted imaging (DWI) demonstrated diffuse high signal intensity in the bilateral cerebral white matter areas. The signal changes on DWI subsequently resolved, and cerebral atrophy resulted. The transient decrease in the cerebral white matter diffusivity seen in the present case may reflect axonal involvement secondary to the glial or neuronal damage in HHV-6 encephalopathy.
