Unilateral abdominal clonic seizures represent a peculiar and rare manifestation of focal onset epilepsy. We present the case of a 26-year-old man with right-sided abdominal clonic movements associated with seizures arising from the left parietal area. We show the ictal EEG correlates of these events, including source localization of early ictal spikes; findings that have not been demonstrated in previously reported cases. The electro-clinical features in this patient suggested that clinical onset occurred after anterior propagation of ictal activity from a region posterior to the neck and trunk area of the sensory homunculus of the postcentral gyrus.
