Preop planning for deep brain stimulation stage I on May 26. This is a limited MRI for preoperative planning. There is mild global parenchymal volume loss commensurate with age. There is no enhancing intracranial lesion, mass, or mass effect. No hydrocephalus. Incidentally noted is a developmental venous anomaly along the right superior frontal gyrus. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. There is mild mucosal thickening in the paranasal sinuses.
Limited examination for operative planning demonstrates no lesions along the expected trajectories of the DBS leads.
