New persistent headache. Abnormality of gait. There is no acute infarct or intracranial hemorrhage. There is no mass, mass-effect, midline shift or herniation. There are few punctate T2-hyperintense foci in the cerebral white-matter, which are nonspecific. Examination is otherwise unremarkable. The ventricles and the other CSF-containing spaces are normal in size. The major intracranial vascular flow voids are preserved. The orbits are grossly unremarkable and mastoid air cells are clear. There is minimal mucosal thickening in the paranasal sinuses.
Noncontrast MRI is essentially within normal limits for age. Few punctate T2-hyperintense cerebral white-matter foci are nonspecific.
