Creutzfeldt-Jakob disease with congophilic kuru plaques: CT and pathological findings of the cerebral white matter.

In a patient whose Creutzfeldt-Jakob disease with congophilic kuru plaques that was proved at necropsy, the early brain CT showed low-density areas in the cerebral white matter before cortical atrophy and ventricular enlargement became apparent. Subsequently, there occurred diffuse white matter lucency and severe brain atrophy. At necropsy, there was severe white matter destruction which was more prominent than cortical neuronal loss. Serial CT scans were of great value for demonstrating the early and predominant changes in the cerebral white matter.
