Personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits [Z86.73], Reason for Study: ^Reason: r/o CVA - stroke protocol History: AMS Brain MRIThere is no evidence of acute ischemic infarct.Encephalomalacia are seen on the left frontal and right parietal lobes indicating chronic ischemic infarctions. Multifocal susceptibility lesions including bilateral frontal and right parietal lobe are again seen, unchanged since prior scan.There is no evidence of acute hemorrhagic lesion on the scan. Patchy FLAIR/T2 high signal intensity lesions on periventricular white matter and centrum semiovale are again seen, indicating nonspecific small vessel ischemic disease, unchanged since prior scan.There is no evidence of abnormal enhancement.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.Brain MRAMotion artifact degraded exam quality.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate there is about 3 to 4 mm sized right paraophthalmic aneurysm, comparing to prior scan, there is no significant interval change. However, due to motion artifact and limitation of MR angiogram, precise evaluation of aneurysm interval change is not possible.There is no other aneurysm seen.There is no evidence of significant (50% or more) intracranial arterial luminal stenosis. Vertebrobasilar system appears to be normal.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Multifocal chronic ischemic lesions and hemosiderin depositions, unchanged.3. Mild to moderate non specific small vessel ischemic disease, unchanged.4. Right paraophthalmic aneurysm, about 3-4mm in size, unchanged in terms of size and configuration since prior scan.5. No other aneurysm was seen. No evidence of significant intracranial arterial luminal stenosis.
