Female, 43 years old, with new left sided headaches and eye pressure. A number of scattered punctate FLAIR hyperintense foci are seen in the cerebral white matter. The cerebral and cerebellar hemispheres and brainstem otherwise show normal signal intensity and morphology. No restricted diffusion is seen.No evidence of parenchymal edema, mass, or mass effect is seen. There is no evidence of intracranial hemorrhage or abnormal extra-axial fluid. The ventricular system is normal in caliber and morphology. On post-contrast images, no pathologic parenchymal or extra-axial enhancement is seen. Signal intensity of the bone marrow is unremarkable. Trace mucosal thickening is present in the sphenoid sinuses.
Scattered punctate foci of FLAIR hyperintensity may represent sequelae of migraine headache, vasculitis, small vessel disease or gliosis from prior inflammation among other etiologies. No definite acute findings are seen.
