memory change Motion artifacts prevent precise evaluation.No evidence of acute ischemic or hemorrhagic lesion on this scan.On FLAIR images, there are patchy high signal intensity lesions especially periventricular white matter and bilateral trigone areas. These lesions are most likely non specific, possibly small vessel ischemic lesions.Left frontal lobe superior frontal gyrus shows focal subcortical high signal intensity lesion which does not show diffusion restriction indicating chronic ischemic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Patchy periventricular and bilateral trigone areas' high signal intensity lesions on FLAIR images indicating possible non specific small vessel disease.Otherwise unremarkable.
