TIA. Brain MRI: There are multiple small areas of encephalomalacia in the left coronal radiata, right frontal lobe centrum semiovale, right thalamus, and left cerebellar hemisphere. There is a background of diffuse patchy cerebral white matter T2 hyperintensity. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a small retention cyst in the right maxillary sinus.Brain MRA: There is no evidence of significant steno-occlusive lesions or aneurysms.Neck MRA: There appears to be mild narrowing of the origins of the bilateral vertebral arteries. There is no otherwise evidence of significant steno-occlusive lesions in the other neck arteries.
1. Multifocal chronic lacunar infarcts and probable chronic small vessel white matter ischemic disease, but no evidence of acute intracranial hemorrhage, mass, or acute infarct.2. Apparent mild narrowing of the origins of the bilateral vertebral arteries, but no evidence of significant steno-occlusive lesions in the rest of the major head and neck arteries.
