Electroencephalogram (EEG) showed mild encephalopathy (Figure 1).
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).

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).
Repeated electroencephalogram (EEG) shows moderate encephalopathy with generalized periodic epileptiform discharges.

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

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).
