57 years, Female, rule out structural cause of amnesia. There is no restricted diffusion involving the hippocampi or elsewhere in the brain. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. There are patchy foci of T2/FLAIR hyperintensity in the bilateral subcortical and periventricular white matter, particularly in the parieto-occipital region, which are nonspecific. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No evidence of acute infarct, hemorrhage, mass or mass effect.2. Mild patchy T2/FLAIR hyperintensity involving the bilateral parieto-occipital subcortical and periventricular white matter which is very nonspecific but may reflect gliosis related to prior inflammation, toxic metabolic injury or small vessel ischemia. Brain MRI is otherwise unremarkable.
