A second head MRI showed low apparent diffusion coefficient (ADC) values and increased DWI-signaling in the left parieto-occipital cortex, characteristic of a cortical ribbon sign (Figure 1), while the electroencephalogram showed periodic sharp-wave complexes (PSWC) over the same area (Figure 2).
EEG showing periodic sharp-wave complexes over the left parieto-occipital region, suggestive of CJD.
