Aims and objectives: The risk associated with surgical treatment of cerebral tumors and vascular malformations (VMs) is particularly important when lesions are located near brain central region.This region comprises the central sulcus and the pre and postcentral gyri,functionally corresponding to the primary motor(M1,B[...]

Methods and materials: 1.Patients selection: This was a prospective study in which we evaluated conventional MRI and fMRI in 18 consecutive patients.This study was performed at Military Hospital of Tunis,Tunisia over a 3 year period (2013-2016).In the present study patients with brain tumors of the central regions eithe[...]

Results: The images of 18 consecutive patients were analyzed. Subjects were all right -handed.The mean age of patients was 51 years (range, 30–81 years). These included 17 patients with tumors and 1 with vascular malformation (VMs).Tumors were localised in the left hemisphere in 11 patients and in the right[...]

Conclusion: Reliable imaging of eloquent tumor-adjacent is necessary for planning function-preserving neurosurgery [6].The gold standard for mapping the eloquent cortex is considered to be intraoperative electrocortical stimulation (ECS) with awake craniotomy. However, this technique is invasive[7] . The use of[...]
