 MRI BRAIN:There are diffusion restriction with T2/FLAIR hyperintensities in the left aspect of the pons, in the right basal ganglia, and in the right temporal lobe, suggestive of acute infarcts. There are a few T2/FLAIR hyperintensities in the subcortical and periventricular white matter suggestive of chronic small vessel ischemic changes. There is minimal compression of the anterior horn of the right lateral ventricle, due to the acute infarct in the right basal ganglia. There is no midline shift. No evidence of acute hemorrhage.MRA BRAIN:The MRA is degraded by severe motion artifacts.MRA demonstrates occlusion of the distal left M1 segment. There are atherosclerotic irregularities of the right middle cerebral artery with no significant stenosis. The right A1 segment is hypoplastic. There are luminal irregularities of the anterior cerebral arteries.There are arteriosclerotic irregularities of the posterior cerebral arteries with small and narrowed right posterior cerebral artery, more than the left. The basilar artery is patent. The right vertebral artery is hypoplastic.
1. Acute ischemic infarcts in the right basal ganglia, right frontal lobe, and the left side of the pons.2. The MRA is severely degraded by motion artifacts. There is occlusion of the distal segment of the left M1. Hypoplastic right A1. The right vertebral artery is hypoplastic. Remainder of the cerebral arteries demonstrates severe atherosclerotic changes.
