Abstract

Magnetoencephalography (MEG) is increasingly used in the non-invasive presurgical evaluation of patients with refractory focal epilepsy. Combination of MEG and magnetic resonance imaging of the brain can estimate the location of the epileptiform discharges. We report a case of a patient with paroxysmal sensory symptoms. All previous investigations where normal, but by the use of MEG we were able to identify the epileptic focus in the insular region. MEG has a better spatial resolution than electroencefalography, and it is more sensitive to tangentially oriented dipoles. MEG should be considered in the workup of patients with refractory focal epilepsy.
