3-D reconstructed magnetic resonance imaging in localization of subdural EEG electrodes. Case illustration

We report an illustrative case of presurgical evaluation for epilepsy surgery, where the three-dimensional reconstructed magnetic resonance imaging played a pivotal role in determining the exact location of the subdural strip electrodes in temporomesial area. The tip of one the frontal strip electrodes was actually recording the temporopolar ictal activity. This contributed conclusively to the decision for surgical treatment and to the excellent outcome.
