Cossu and colleagues present their outcome of stereotactic radiofrequency lesioning in nodular heterotopia and show a remarkable rate of Engel class I outcome.1 This adds to the growing volume of publications using stereotactic invasive lesioning combined with high-resolution MRI and invasive stereotactic EEG (SEEG) recordings allowing for a three-dimensional physiological characterisation of the epileptogenic focus techniques used. These are radiofrequency thermoablation,2 laser–guided thermoablation3and interstitial radiosurgery,4 and entities-treated range from hippocampal sclerosis to nodular heterotopias to hypothalamic hamartomas.
Stereotactic radiofrequency lesioning in focal epilepsy has been tried in the past relying on anatomy, brain atlases and …
