False lateralization of functional neuroimaging methods is rare during presurgical evaluation of epileptic patients. Both interictal and ictal EEG incorrectly lateralize the epileptogenic region (ER) in about 10% of patients [1]. Interictal single photon emission computed tomography (SPECT) shows a false lateralization in 10% of cases [2]. Even reliable ictal lateralizing signs to the contralateral hemisphere, such as clonia, or unilateral [...]
