EEG-fMRI coregistration in non-ketotic hyperglycemic occipital seizures

SummaryWe report the first case, to our knowledge, of non-ketotic hyperglycemic (NKH) related occipital seizures studied by continuous EEG-fMRI in an undiagnosed diabetic patient. Ictal EEG showed left posterior spikes and sharp-waves. Seizures subsided after insulin therapy was started.Continuous EEG-fMRI was performed and BOLD activation was identified in the left Brodmann's area 18 (visual association area).Activation of an epileptic focus related with the patient's metabolic disturbance can be postulated.
