Fig. 1

CT and MRI showed a CM located in left basal ganglia (a). Diffusion tensor tractography delineated pyramidal tracts and combined with T2 MR Image (b). After assessing the relationship between pyramidal tracts and CM via Virtual Reality, posterior lateral approach was chosen as shown by green arrow (c). CM was accessed through posterior lateral approach with the guidance of neuronavigation (d). Intraoperative images showed lesion exposure (e), subcortical stimulation mapping for pyramidal tracts in perilesional region (f), and total removal of CM (g). Preoperative VR image showed CM close to the pyramidal tracts (h), postoperative VR images showed total removal of Cm without damage to the pyramidal tracts (i)
