Unspecified dementia without behavioral disturbance [F03.90], Reason for Study: ^Reason: small vessel disease extent History: memory changes No evidence of acute ischemic or hemorrhagic lesion on the scan.Multifocal scattered FLAIR/T2 high signal intensity lesions involving bilateral periventricular white matter, centrum semiovale as well as pons are seen, indicating nonspecific small vessel ischemic disease.There are localized round susceptibility lesions on the right side centrum semiovale without evidence of surrounding edema or mass effects indicating possible chronic petechial hemorrhage or calcifications on Gradient echo images.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. The mastoid air cells are clear. Fluid collection seen on the right side sphenoid sinus.Bilateral lens are not seen indicating postoperative status.
1. Nonspecific small vessel ischemic disease as described above.2. No evidence of acute ischemic or hemorrhagic lesion.
