Right DBS, now planning for left DBS. There are postoperative findings related to right deep brain stimulator insertion. The electrode passes through the right lateral ventricle and region of the right globus pallidus and terminates in the region of the superior margin of the right cerebral peduncle. There is mild diffuse cerebral volume loss. There is a punctate focus of susceptibility effect adjacent to the left superior frontal sulcus, which is nonspecific. There is no midline shift or herniation. The major intracranial vessels are unremarkable.
Preoperative planning MRI demonstrates a right deep brain stimulator in position.
