Continuous electroencephalography (CEEG) showing a continuous delta slowing maximum in the bifrontal regions captured before the onset of choreiform movements. The patient was not on any continuous sedation during this period that would alter their level of consciousness. No seizure activity noted. (Bipolar montage; LF 1.6 Hz, HF 70 Hz, sensitivity 7 uV; 15 s Epoch).

In the MICU, EEG revealed bilateral cortical dysfunction, max in the left frontotemporal region and severe diffuse encephalopathy with no epileptiform discharges (Figure 2).
Magnetic resonance imaging (MRI) of the brain showing diffusion weighted imaging (DWI; images (a), (c), and (e)) and apparent diffusion coefficient (ADC; images (b), (d), and (f)) sequences. Restricted diffusion noted in the subcortical white matter (a and b), corpus callosum (c and d), and globus pallidus (e and f).

An MRI completed on hospital day 5 revealed bilateral restricted diffusion in the cerebral white matter, and bilateral globus pallidus, corpus callosum, and bilateral hippocampus in the medial temporal lobes with scattered punctate restricted diffusion in the bilateral cortex and cerebellum consistent with posthypoxic leukoencephalopathy and global hypoxic ischemic injury (Figure 3).
