74-year-old female with leg weakness. Small focus of restricted diffusion in the left parietal subcortical white matter. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Scattered foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter and brainstem, which are nonspecific, but compatible with chronic small vessel ischemic changes. Focal encephalomalacia compatible with remote right cerebellar hemisphere infarction. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preservedSella and orbits are grossly within normal limits. Small amount of fluid and mucosal thickening in the left maxillary sinus. Bone marrow signal and extracranial soft tissues are within normal limits.
1. Small focus of acute ischemia in the left parietal subcortical white matter likely related to small vessel infarction.2. Moderate chronic small vessel ischemic disease.
