[Correlation of diffusion-weighted magnetic resonance imaging with neurological deficits in sporadic Creutzfeldt-Jakob Disease].

This case report describes the sporadic Creutzfeldt-Jakob disease (CJD) of a 53-year-old man who initially complained about vertigo and dizziness. Within 18 weeks, he developed impaired memory, hemineglect, and sensory impairment of the left half of the body. A CSF tap was positive for 14-3-3 protein and showed increased tau protein, neuron-specific enolase (NSE), and the astroglial protein S-100 B. The EEG showed right temporal sharp waves without periodicity. Diffusion-weighted MRI revealed hyperintensities in the right temporo-occipital cortex which corresponded well with hypometabolic areas in a PET scan and the neurological and neuropsychological deficits. The morphological FLAIR T2 MRI showed no pathological changes. Within 20 weeks, the patient developed severe dementia with decreased spatial orientation and myoclonia, became incontinent, and was confined to bed. He died within 22 weeks after the first presentation of symptoms.
