We present the case of a 55-year-old male with Parkinson’s disease who underwent staged DBS surgery. After placement of the electrodes in the left brain, the patient exhibited altered mental status that terminated the procedure and prevented placement of electrodes in the right brain. CT and MRI scans showed a small intracranial hemorrhage in the left dorsolateral STN. The patient recovered with no permanent adverse effects and was successfully implanted one month later. However, the patient reported substantial reduction in his right-sided tremor following the ICH. The stimulator in the left brain was thus left off for approximately one year.
