Left face and arm numbness. MRI: There is no evidence of intracranial hemorrhage or acute infarct. There are multiple nonspecific foci of high T2 signal in the periventricular white matter. The brain parenchyma otherwise appears unremarkable. There is a small extra-axial T2 hypointense lesion along the left parietal convexity. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRA: The intracranial internal carotid arteries are normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. There is a hypoplastic T1 segment of the right posterior cerebral artery with a relatively prominent right posterior communicating artery. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or aneurysm.
1. No evidence of acute intracranial hemorrhage, mass, or acute infarct. Nonspecific foci of T2 hyperintense signal in the supratentorial white matter may represent mild chronic small vessel ischemic disease.2. No evidence of flow-limiting stenosis, occlusion, or aneurysm in the major intracerebral arteries.3. A small extra-axial T2 hypointense lesion along the left parietal convexity may represent a meningioma, but is incompletely characterized.
