Abstract
|
|
|
|
Sporadic Creutzfeldt-Jakob disease (CJD) is a rare progressive spongiform encephalopathy. Involuntary movements commonly occur in the course of sporadic CJD, but focal dystonia alone as an initial manifestation is rare. We described a 40-yr-old man who presented with a 2 week history of focal dystonia in the neck and left arm. Interestingly, diffusion-weighted images revealed high signal intensities in the right temporal, posterior parietal, and occipital cortices rather than in the striatum.
