49 years, Male, with history of TIA causing left-sided weakness and dysarthria. 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. Foci of T2/FLAIR hyperintensity are seen in the periventricular white matter, which 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 diffuse opacification of the bilateral mastoid air cells. Bone marrow signal and extracranial soft tissues are within normal limits. Redemonstration of cystic lesions with T1 hyperintensity at the nasopharynx, with a dominant lesion seen on the right, measuring 21 x9 mm. Smaller lesions are seen on the left.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. Again seen are few foci of T2/FLAIR hyperintensity in the supratentorial white matter, which are nonspecific but may represent mild chronic small vessel ischemic changes. 2. Redemonstration of multiple cystic lesions in the nasopharynx likely representing mucous retention cysts.
