case_images: Electroencephalogram (EEG) findings. The patient EEG, recorded in the acute phase two days after the admission, shows continuous high-amplitude rhythmic 3-5 Hz slow waves and sporadic diphasic sharp waves over the left fronto-centro-temporal derivations.

case_images: The patient underwent a video-electroencephalogram (video-EEG) recording, which showed continuous high-amplitude rhythmic 3-5 Hz slow waves and sporadic biphasic sharp waves over the left fronto-centro-temporal derivations (Fig. 1).
case_images: Magnetic Resonance Imaging (MRI) brain findings The panel depicts the patient's MRI scans taken (performed in the acute phase two days after the admission). A) and B) coronal Fluid-attenuated Inversion Recovery (FLAIR) T2-weighted images, C) and D) axial FLAIR T2-weighted images show hyperintense alterations in the left temporo-fronto-parietal cortex.

case_images: Additional brain MRI scans were performed, which now showed hyperintense alterations over the left temporo-fronto-parietal cortex in fluid-attenuated inversion recovery T2-weighted sequences (Fig. 2).
