T2 and FLAIR images show hyperintense lesions in bilateral frontal lobes and thalamic and mesiotemporal regions (better seen on coronal FLAIR images). T1-weighted images show no contrast enhancement after gadolinium injection.

T2 and FLAIR bilateral frontal hyperintensity spreading to thalamic and mesiotemporal areas, without gadolinium enhancement (Fig. 1).
(A) Interictal EEG characterized by diffuse slowing and frontal spike-waves. (B) Ictal EEG characterized by subtle SE of frontal origin.

The EEG showed successively a drug-induced burst-suppression state, generalized periodic epileptiform discharges, a diffuse slowing with subtle seizures of frontal origin, and a progressive return of alpha rhythm (Fig. 2).
