Parkinson's preoperative planning for DBS. There is blurring of the susceptibility effect in portions of the bilateral substantia nigra. There is a nonspecific punctate focus of susceptibility effect in the right parietal lobe periventricular white matter. There are also mild nonspecific scattered cerebral white matter T2 hyperintensity. There is no evidence of intracranial mass. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is a right lens implant and scleral band and atrophy of the right optic nerve.
Findings supportive of Parkinson's disease. Otherwise, unremarkable preoperative MRI of the purposes of preoperative planning.
