What is lesional epilepsy?
In some patients with long-standing epilepsy, the cause of the seizure may be slow-growing tumors, vascular malformations (an abnormal clump of blood vessels in the brain), infections or congenital abnormalities. These lesions are picked up on the magnetic resonance imaging (MRI) scan. Removal of a lesion may cure a patient’s epilepsy. These patients are best evaluated at a comprehensive epilepsy center.
