Male, age 9. Right parietal Glioma with epilepsy. Corticography also showed interictal discharges in the frontal lobe, though the majority of seizures were of parietal origin. This was a complex multifocal case, where prior clinical assessment using EEG had been inconclusive (non-localizing), leading to the patient's referral for MEG. Following the MEG, was operated in the right parietal area and is now partially seizure free.
