Post-surgical MRI following tumour vs. epilepsy surgery. (A, C) MRI 40 months after first surgery (at age 14 months). (B ,D) MRI after repeat surgery at age 6 years. The red dot in (C) indicates seizure onset recorded from subdural grids, strips, and depth electrodes. Broca's area could not be determined by direct electrical cortical stimulation, however, based on the result of invasive recording, a resection of the pars triangularis and pars opercularis frontalis was not necessary.
