MRI of the brain ((a) DWI sequence, (b) FLAIR sequence) on day 3 after presentation, showing extensive areas of restricted diffusion with associated FLAIR hyperintensity involving bilateral temporal lobes, bilateral insular, bilateral frontal, and parietal regions in cortical and subcortical areas and diffuse mild effacement of the cerebral sulci.

An MRI of the brain on day of transfer showed extensive areas of restricted diffusion with associated FLAIR hyperintensity involving bilateral temporal lobes and bilateral insular, bilateral frontal, and parietal regions in cortical and subcortical areas and diffuse mild effacement of the cerebral sulci (Figure 1), without enhancing lesions.
EEG on hospital day 3, showing theta frequency slowing and artifacts from spontaneous horizontal and vertical eye movements but no triphasic activity and no epileptiform activity. HFF 70 Hz, LFF 1 Hz; sensitivity and time base indicated on image.

Continuous electroencephalogram (cEEG) for a duration of 96 hours showed continuous, irregular, generalized low voltage slowing (Figure 2); however, intermittently observed facial and lip twitching did not have an electrographic correlate on cEEG.
