 There are scattered foci of T2 hyperintensity within the subcortical and periventricular white matter, primarily subcortical in location. Many of these were present on the 2006 study, with a few that are new. None demonstrate mass effect, restricted diffusion, susceptibility abnormality, or enhancement. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is unremarkable. 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. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
