Male, 58 years old, with Parkinson's disease, pre-DBS evaluation. No enhancing lesions are seen. A chronic appearing lacunar infarct of the right basal ganglia is noted. Mild additional scattered areas of periventricular T2 hyperintensity are seen likely indicating microvascular ischemic disease. There may be some obscuration of the substantia nigra and red nucleus on the right as visualized on 3-D T2 weighted images, though this sequence is artifact prone and the findings may not be reliable. It does appear that there are scattered prominent perivascular spaces within the midbrain. The left temporal horn and atrium are more prominent than on the right which may reflect anatomic variation. Diffuse paranasal sinus mucosal thickening is seen particularly affecting the ethmoid air cells.
Limited sequences are provided for surgical planning purposes. No acute intracranial abnormalities are suspected.
