Left eye flashes, workup for TIA. No restricted diffusion to suggest acute infarct. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. There are patchy confluent areas and scattered foci of T2/FLAIR hyperintensity in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with chronic small vessel ischemic disease. Punctate foci of susceptibility consistent with chronic microhemorrhage are noted involving the right frontal lobe and left occipital lobe. There is global parenchymal volume loss which is commensurate with age. Major flow-voids are preserved. Sella and orbits are grossly within normal limits. Minimal mucosal thickening is seen in the frontal and maxillary sinuses; paranasal sinuses are otherwise clear. Minimal left mastoid air cell fluid. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No evidence of acute infarct. No intracranial mass or mass effect.2. Foci of T2/FLAIR hyperintensities in periventricular and subcortical white matter are nonspecific but compatible with mild chronic small vessel ischemic disease.3. Two punctate foci of chronic microhemorrhage are nonspecific but given the peripheral lobar distribution, favor amyloid angiopathy.
