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.

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).
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.

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).
