Intracranial localisation of ictal urinary urge epileptogenic zone to the non-dominant temporal lobe

Ictal urinary urge is a rare symptom of focal epilepsy usually localising to the non-dominant hemisphere, specifically, the temporal lobe. Lateralisation in previously described cases has been established usingscalp video-EEG monitoring or functional imaging. We report the case of a 19-year-old girl with refractory epilepsy and ictal urinary urge arising fromthe non-dominant temporallobe, confirmed by invasive, subdural EEG monitoring. Since undergoing a temporal lobectomy two and a half years ago, the patient has not experienced ictal urinary urge. To our knowledge, this is the first report demonstrating localisation of ictal urinary urge epileptogenic zone to the non-dominant temporal lobe by invasive intracranial monitoring.
