Reason: r/o structural lesion or infarct History: left sided numbness Exam is limited by motion artifact.There is superficial siderosis of the right cerebral hemisphere predominantly at the convexity with some staining of the sylvian fissure. This likely represents the sequela of prior subarachnoid hemorrhage. No acute intracranial hemorrhage is suspected. No abnormal diffusion restriction. No evidence of intracranial mass, mass-effect, or midline shift. No extra-axial fluid collections. The ventricles, sulci, and cisterns are normal in size without evidence of hydrocephalus. There are nonspecific scattered periventricular and subcortical white matter T2 hyperintensities, which may represent chronic small vessel ischemic disease. There is opacification of the bilateral maxillary sinuses. The imaged orbits are intact. The osseous structures are unremarkable.
1.No acute ischemia.2.Moderate chronic small vessel ischemic disease.3.Superficial siderosis of the right cerebral hemisphere, predominantly at the convexity, likely sequela of prior subarachnoid hemorrhage.
