Initial MRI brain. (A) T2-FLAIR showing T2 hyperintensities (white arrow heads) in bilateral frontal and insular cortices and medial thalami. (B) Diffusion-weighted image showing diffusion-restricting lesions (white arrow heads) in the bilateral frontal and insular cortices and medial thalami. (C) Post-contrast T1 showing areas of bilateral frontal cortical enhancement (white arrow heads) corresponding to areas of frontal DWI/FLAIR abnormality.

EEG demonstrating non-convulsive status epilepticus.The settings for EEG are double banana montage, 10s epoch and sensitivity of 5 microvolts. The clip demonstrates non-convulsive status epilepticus characterized by polymorphic 1-2-Hz right frontal polymorphic waves with superimposed fast and rhythmic activity.
