Serial computed tomography findings in Creutzfeldt-Jakob disease

Serial CT investigations of 3 patients with histologically confirmed Creutzfeldt-Jakob disease revealed persisting slight brain atrophy to progressive extreme atrophy corresponding to the absolute, not the individual duration of illness. No correlation was observed between CT findings and the patients' condition or electroencephalographic results. In one case with a duration of about 16 months and a terminal brain weight of 750 g a massive bilateral, later unilateral subdural hygroma appeared which probably was caused by retraction of the brain showing an enormous atrophy.
