Summary We aimed at determining the lateralizing and localizing values of “hemiballic‐like” ictal movements observed in some partial seizures. Among 20 patients disclosing ictal hyperkinetic features and explored by stereotactic‐EEG (SEEG), this sign was observed in four patients. In these cases, hemiballic movement was ipsilateral to the ictal‐onset zone and was associated with contralateral ictal dystonia. Noninvasive and subsequent invasive recording revealed seizure origin in the inferior parietal lobule or the parietal operculum in three patients and in the inferior prefrontal cortex in one.
