Other amnesia [R41.3], Reason for Study: ^Reason: h/o MS, hospitalizations in last year with mental status changes, increased short term memory deficits. Evaluate for progression of MS History: memory problems Re-demonstration of bihemispheric multiple high signal intensity white matter lesions on FLAIR/T2 images, unchanged in terms of number and each lesions' size since prior scan.There is no evidence of new abnormal signal intensity lesion.There is no evidence of acute ischemic or hemorrhagic 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, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Right posterolateral ethmoid sinus shows retention cyst.Left eye lens is not seen possible prior lens surgery.Nasal septal deviation toward left.
