Anatomical positions of the right and left DBS electrodes. Images show coronal, axial, and sagittal MRI with superimposed modified Schaltenbrand- Bailey Atlas, and 3D rendering of the measured electrode. The targeted red structure is the GPi, and the more dorsal green structure is the GPe. The dark red line traversing the image and the red X represent the lead trajectory and position. In the 3D rendering, the dark gray structure is the GPi, and the light gray structure is the GPe. The white regions of the rendered DBS lead represent contacts numbered 0 to 3 and dark red represents insulation.

Postoperative lead localization and three-dimensional (3D) mapping identified that both leads were appropriately placed in the postero-latero-ventral GPi (Figure 1).
