In this difficult to localize group of patients, if the peak of the primary cluster of the EEG-fMRI results was not resected the surgical outcome was likely to be poor: for the high confidence level, no patient had a good outcome, and for the medium and low level, only 18% and 28%, respectively had a good surgical outcome. The resection of the primary EEG-fMRI cluster is therefore necessary to obtain a good outcome, but not sufficient: the positive predictive value remains low (43%-52%) for all confidence levels. For the high confidence cases, EEG-fMRI provides information on the location that needs to be resected but does not indicate its extent.
