I am having moderate to severe short term memory loss. What does this report mean? Exam: MRI of the brain without contrast. Technique: MRI of the brain was performed in the sagittal and axial plane with T1, T2, gradient echo and FLAIR sequencing. In addition, diffusion axial images were taken of the entire brain. The ventricles are normal in size, shape and configuration. No shift of midline structures. No abnormal extra-axial fluid collections. There were scattered nonspecific foci of abnormal signal in the subcortical white matter of both cerebral hemispheres. Differential diagnostic considerations would include microvascular changes, demyelination, nonspecific posttraumatic or inflammatory gliosis and sequela from chronic migraines or seizures. There was no evidence of an acute territorial area of infarction or mass lesion. Flow void is seen in the carotid siphon and basilar artery tip indicating patency. The craniocervical junction is normal. No areas of restricted diffusion. The pituitary sellar dimensions are within normal limits. The mastoid air cells are well pneumatized. The IACs are normal. Mucosal thickening in the ethmoid and maxillary sinuses. Impression: 1. Nonspecific foci of abnormal signal within the subcortical white matter both cerebral hemispheres most likely early chronic ischemic microvascular changes in this age group. 2. Mucosal thickening in the ethmoid and maxillary sinuses.
