case_images: (From left to right) Axial, coronal, and sagittal views of MRI brain with contrast demonstrating a previously treated arteriovenous malformation in the right lingual gyrus with evidence of gliosis. RFA, R: right. LHP, L: left. A: anterior. P: posterior. LHP: left horizontal position

case_images: The AVM was abutting the calcarine sulcus in the primary visual cortex (Figure 1).
case_images: Axial (A) and coronal (B) views of MRI brain with a superimposed SEEG depth electrode implanted in the right pulvinar nucleus. Coronal (C) and (D) sagittal three-dimensional reconstruction of CT brain demonstrating implanted SEEG depth electrodes.. SEEG: stereoelectroencephalography

case_images: A-C. Electrographic recordings as seen in the OSUP contacts 6-7, OLAT contacts 5-6, and PULV contacts 1-3. Leads during a clinical seizure, with propagation of activity from the OSUP and OLAT leads in panel A, to the PULV lead approximately six minutes later in panels B and C. OSUP: occipital superior; OLAT: occipital lateral; PULV: pulvinar

case_images: Seizure activity ultimately propagated to involve the other, more anterior electrodes later during the episode, including pulvinar electrodes later in this recording, which culminated in a generalized tonic-clonic seizure (Figures 3A-3C). 
case_images: Long episode detection of high amplitude discharges in the superficial lateral contacts of the RNS system in the lateral occipital leads, labeled Latr3 - Latr4. Latr: lateral, Supr: superior, RNS: responsive neurostimulation

case_images: The system detected high amplitude discharges reaching saturation thresholds in both leads after the detection of epileptiform discharges (Figures 4, 5).
case_images: Fifteen-second ECOG recording as seen from the RNS system, labeled saturation, provoked by the detection of discharges (in yellow) with amplitudes above the threshold of detection of the lateral occipital RNS leads. Latr: lateral, Supr: superior, RNS: responsive neurostimulation
