Altered mental status. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is scattered cerebral white matter T2 hyperintensity. There are also small areas of encephalomalacia in the bilateral basal ganglia and corona radiata. There is prominent low T2 signal in the bilateral basal ganglia. The ventricles and basal cisterns are unchanged in size and configuration. There is diffuse cerebellar volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is minimal fluid signal in the left mastoid air cells. There is diffuse paranasal sinus mucosal thickening. There is leftward nasal septal deviation with spur.
1. No evidence of acute intracranial hemorrhage, mass, or acute infarct.2. Probable chronic small vessel white matter ischemic disease and chronic bilateral basal ganglia and corona radiata lacunar infarcts. 3. Nonspecific diffuse cerebellar volume loss.
