Other amnesia [R41.3], Reason for Study: ^Reason: memory difficulties History: memory difficulties There is no evidence of acute ischemic or hemorrhagic lesion.Patchy confluent FLAIR/T2 high signal intensity lesions on bilateral periventricular white matter and centrum semiovale. The white matter lesions are non specific thus could indicate extensive non specific small vessel ischemic disease (leukoaraiosis) , however, cannot completely exclude possibility of demyelinating disease.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 paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Extensive white matter lesions on FLAIR/T2 images indicate possible advanced non specific small vessel ischemic disease or demyelinating disease.
