We describe a 30-year-old female with intractable symptomatic epilepsy caused by an insular calcified mass, which was histologically proved as psammomatous meningioma. Seizures were described as consciousness impairment, motionless stare and automatism. After total removal of the tumor with a neuronavigation system and motor evoked potential (MEP) monitoring, seizures completely disappeared without neurological deficit. We emphasize that insular meningioma presents complex partial seizures which mimic medial temporal lobe epilepsy and seizures are controlled by total resection of the tumor.
