Axial MRI diffusion weighted images (top row) and fluid-attenuated inversion recovery images shown at about one month (a), four months (b), and nine months (c) from onset of symptoms. These images show no diffusion restriction on diffusion weighted images or hyperintensities on FLAIR that would support the diagnosis of Creutzfeldt-Jakob disease.

MRI brain at one month after symptom onset showed no diffusion restriction (Figure 1).
Electroencephalogram (EEG) completed at about nine months from the onset of symptoms. The occipital dominant rhythm was 9 Hz. EEG activity was reactive to stimulation. There were no 1-2 Hz periodic sharp wave complexes suggestive of Creutzfeldt-Jakob disease.

Three months after onset of symptoms, a routine EEG was ordered by the local neurologist which was unrevealing (Figure 2).
