 Redemonstrated is diffuse volume loss without specific lobar predominant atrophy, unchanged in extent. There are no findings of ventricular obstruction or hydrocephalus. T2 hyperintense abnormality is present in periventricular and subcortical white matter locations as well as within the pons which do not have associated mass effect or restricted diffusion and do not enhance. 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. Mucosal thickening is again noted within the inferior left maxillary sinus. Otherwise the remaining paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
1.Stable diffuse volume loss without a specific lobar predominant atrophy pattern.2.Stable chronic small vessel ischemic disease.
