 The study is partially motion degraded and repeated sequences were performed when possible. Given this caveat:There are scattered punctate to small foci of T2 hyperintensity within the subcortical white matter without associated mass effect, restricted diffusion, susceptibility abnormality, or enhancement. There are no similar findings involving the posterior fossa structures.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. A small retention cyst versus polyp is noted in the left maxillary sinus. The remaining paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
1.The study is partially motion degraded and repeated sequences were performed when possible.2.There are scattered punctate to small foci of T2 hyperintensity within the subcortical white matter without associated mass effect, restricted diffusion, susceptibility abnormality, or enhancement. There are no similar findings involving the posterior fossa structures. These findings are nonspecific and the differential diagnosis would most likely include small vessel ischemic disease, migraine sequelae, although given lesional location and morphology demyelination is felt to be less likely.
