 Several sequences are motion degraded. Given this caveat:T2 hyperintense foci are present throughout the white matter, basal ganglia, and pons, confluent in some locations. This is not associated with restricted diffusion, susceptibility abnormality, or enhancement. There is diffuse volume loss, slightly more affecting the bilateral mesial temporal lobes. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Note is made of dolichoectasia and elongation of the posterior circulation. Mucosal thickening is present within a single right ethmoid air cell. Otherwise the paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
