46 years, Female, right-sided numbness. Rule out stroke.. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. There is a nonspecific focus of FLAIR hyperintensity in the left frontal centrum semiovale. Minimal additional scattered foci of T2/FLAIR hyperintensity in the supratentorial white matter are nonspecific, but compatible with minimal chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. There is minimal bilateral mastoid air cell opacification. There is also minimal scattered paranasal sinus mucosal thickening, relatively greater in the left posterior ethmoid region. Cystic foci in the midline nasopharyngeal region are compatible with Tornwaldt cyst.
1. Brain parenchyma is essentially unremarkable for age. 2. There are minimal scattered foci of T2/FLAIR hyperintensity in the white matter, including a relatively more prominent focus in the left frontal lobe. These are nonspecific but may represent minimal chronic small vessel ischemic changes. The left frontal focus described above may also be related to prominent perivascular spaces in this region which are a normal variant.
