 There are a few scattered punctate foci of T2 hyperintensity within bifrontal subcortical white matter without associated mass effect, restricted diffusion or enhancement. There are no similar appearing lesions in the posterior fossa. 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.
There are a few scattered punctate foci of T2 hyperintensity within bifrontal subcortical white matter without associated mass effect, restricted diffusion or enhancement. These are nonspecific in appearance and the differential diagnosis would most likely include small vessel disease, migraine sequelae, or residua from previous head trauma.
