(Case 28, Table 1, group nn, decision type 1.): A drug-resistant epileptic patient with the electroclinical features of humming epilepsy. a Video-EEG monitoring: during one of his habitual seizure, a right frontotemporal seizure activity was registered (red arrows). Originally, he was nonlesional and this MRI-status did not change yet after this study. b and c 18F-FDG PET and PET/MRI presented a bitemporal hypometabolism with a right predominance (red boxes) and d a left cerebellar hypometabolism (red box). c This patient remained as an iEEG candidate. iEEG monitor has been performed and showed a bitemporal seizure activity with a left side onset (red arrows, left side of the figure), a left-right propagation in between a 10-s interval (red arrows, right side of the figure), which was remote-controlled by a possible left orbitofrontal seizure onset zone. The patient did not allow neither a second iEEG intervention, nor VNS or DBS implantation
