Lower extremity weakness. Fall. Confusion. Atrial fibrillation. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild T2 hyperintensity with volume loss in the left medial occipital lobe, compatible with a chronic infarct. There is mild ex vacuo dilation of the occipital horn of the left lateral ventricle. There is minimal high T2 signal bilateral periventricular white, which likely represents chronic small vessel ischemic changes. There is no midline shift or herniation. There is possibly a 4 mm outpouching of the right internal carotid artery within the cavernous sinuses. The skull and extracranial soft tissues are unremarkable. There are bilateral lens implants.
1. Limited exam demonstrates a chronic left posterior cerebral artery territory infarct, but no evidence of acute cerebral infarction.2. Possible apparent 4 mm outpouching of the right internal carotid artery within the cavernous sinuses, which may be to to slice selection effects of the normal curving vasculature versus an aneurysm. Further evaluation via CTA or MRA may be useful for further elucidation.Findings conveyed to Dr. Gao by telephone on 4/18/15 at 10:55am.
