case_images: Electroencephalogram (EEG) showed mild encephalopathy (Figure 1).
case_images: T2-weighted FLAIR MRI images on the axial (top left) and coronal (top right) planes exhibit abnormal hyperintense signals involving the cortices of both occipital lobes consistent with encephalitis. T1-weighted post gadolinium shows no enhancement of the affected occipital lobe (bottom left) and MR angiogram (MRA) is normal with no evidence of vasculitic changes (bottom right).

case_images: T1-weighted post gadolinium showed no enhancement of the affected occipital lobe and MR Angiography (MRA) was normal with no evidence of vasculitic changes (Figure 2).
case_images: Repeated electroencephalogram (EEG) shows moderate encephalopathy with generalized periodic epileptiform discharges.

case_images: His repeated EEG demonstrated moderate encephalopathy with generalized periodic epileptiform discharges (Figure 3).
case_images: Plain (top left) and contrasted (top right) CT scans show progressive/enlarging hypodense encephalitic changes in both occipital lobes.

case_images: The repeated CT brain showed involvement of high parietal lobes bilaterally which were not seen in the previous imaging; and progressive/enlarging hypodense encephalitic changes in both occipital lobes (Figure 4).
