We evaluated the correlation between the periodic sharp wave complexes (PSWC) on EEG and the spreading lesions on diffusion-weighted (DW) magnetic resonance images (MRI) in two cases of Creutzfeldt-Jakob disease (CJD). In Case 1, DW-MRI showed increased signal intensity in bilateral caudate, bilateral parietal, and right temporo-occipital cortex at 7 weeks after onset. EEG showed PSWC of 1Hz fr...
