Figure 2. MRI features suggestive of sCJD with slight
progression of signal abnormalities. Short-term follow-up axial
T2-weighted FLAIR images (a) show similar subtle cortical
hyperintensities, again best appreciated in the right parietal cortex
(grey arrow). Axial diffusion-weighted images (b) and apparent diffusion
coefficient maps (c) show persistent and slightly more pronounced
bilateral diffusion restriction in multiple cortical regions, caudate
nuclei, and anterior putamina (white and black arrows).
Follow up awake EEG revealed pathologic diffuse slowing of background
activity and bilateral periodic polyphasic sharp wave complexes,
dominating in right frontal-temporal area (Figure 3).
