Introduction

A 39-year-old ambidextrous female with medically refractory seizures presents with seizures consisting of a loss of awareness. Scalp video-EEG monitoring showed interictal epileptiform discharges arising from both left and right anterior temporal regions. The typical clinical seizures showed ictal EEG changes that were classified as left frontotemporal, right frontotemporal, or non-localizable. The MEG showed a tight dipole cluster in the left anterior temporal region as well as a single dipole in the right temporal region. Both 3 T brain MRI and VBM were normal.
