Clinical question: Preoperative planning. Signs and symptoms: Seizure. Pre and post enhanced fusion brain MRI:Examination performed as a surgical guidance and is not a true diagnostic test.There are bilateral deep brain electrodes placed via bilateral occipital approach. The electrodes bilaterally extending along the medial aspect of bilateral temporal lobes and terminate along the medial aspect of bilateral temporal tips. These increased T2 signal intensity along the entire course of left electrode and only posteriorly along the course of the right electrode in the right posterior temporal-occipital region. Ventricular system are within normal size and with maintained midline.
Pre and postcontrast enhanced fusion brain MRI as detailed above.
