Abstract: Objective: To describe a multimodal approach including structural MRI, functional magnetic resonance imaging (fMRI), and intraoperative electrocorticography (ECoG) with cortical stimulation for surgical planning of an extensive lesion involving the central area. Patient and methods: A 23-year-old right-handed woman with intractable epilepsy and mild left hemiparesis, after preoperative investigation including EEG, structural MRI and fMRI, she underwent surgery guided by ECoG and cortical stimulation. Results: fMRI showed a displacement of the cortical representation for her left hand which was confirmed by intraoperative cortical stimulation. Surgical resection involved the lesioned central area, particularly the anatomical precentral gyrus, sparing the displayed hand motor area. The early post-operative follow-up showed no further deficit, but an improvement of manual dextricity. Conclusion: This report shows the role of the multimodal investigation in localizing accurately both the epileptogenic focus and functional areas, in patients with epileptogenic lesions impinging eloquent cortex.
