[Sequence of clinical changes and evolution of MR images in a case of chronic SSPE]

Slow course case of subacute sclerosing panencephalitis is reported. The onset was at the age of 16 years and death followed after 5 years. He was observed during nine successive hospitalizations and the authors describe the changing clinical symptomatology parallelly with successive EEG records and brain MR imaging evolution. Successive phases of the disease were associated with hyperintense changes in T2-weighted.images, and were situated initially in occipital lobes, and involved later on periventricular areas and finally the whole white matter of both cerebral hemispheres. Subcortical brain atrophy developed parallelly.
