Gelastic seizure is a rare type of seizure characterized by bouts of uncontrolled, stereotyped laughter and often associated with hypothalamic hamartomas. In this case study we review a patient with a low grade ganglioglioma in the temporal lobe, a rare type of brain tumor that commonly causes seizures. The 8-year-old ambidextrous patient presented with seizures starting four days prior to presentation, happening multiple times daily and with each seizure lasting for 5–15 s. The patient's neurological examination was normal between episodes, and VEEG recorded ictal laughing events originating focally from the anterior temporal and/or inferior frontal region. Seizures were stopped with Levetiracetam, however given MRI findings surgical intervention was additionally deemed necessary. MRI head with contrast showed 8 mm nodular enhancing lesion located in the anteroventral portion of the right temporal pole with surrounding edema that extended to the anterior margin of the fusiform gyrus. The patient recovered well from surgery with no neurological deficits, is no longer on any antiseizure medications and remains seizure free at 3-year follow-up.
