 There are 2 small foci of T2 hyperintensity in right frontal subcortical white matter, and one in left frontal subcortical white matter, without associated 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 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. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.

These are nonspecific in appearance and the differential diagnosis would most likely include small vessel disease, migraine sequelae, or residua from past trauma. Given lesional location and morphology, demyelination is to be unlikely.
