79 years, Male, memory loss. There is moderate global parenchymal volume loss without a particular lobar distribution. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with chronic small vessel ischemic changes. There is a focal area of volume loss involving the left posterior cerebellar hemisphere. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. There are bilateral lens implants. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No intracranial mass or mass effect. No extra-axial collections or hydrocephalus.2. Mild chronic small vessel ischemic changes. Small focal area of volume loss involving the left posterior cerebellar hemisphere which may be related to chronic infarct. 3. Moderate global parenchymal volume loss without a particular lobar distribution.
