Endovascular ablation of a temporal lobe epileptogenic focus - a complication of Wada testing

The authors report on a patient with a long history of medically refractory temporal lobe epilepsy. During pre-operative evaluation for anterior temporal lobectomy he underwent a Wada test for speech and memory lateralization. During the procedure, he suffered a focal cerebral infarct, within the right medial temporal lobe, at the site of the epileptic focus. This resulted in the resolution of his seizure disorder. The possibility of endovascular management of seizure disorders of the temporal lobe should be investigated further as a potentially minimal invasive therapeutic option for medically intractable epilepsy.
