Weakness with possible recent TIA. Evaluate for acute abnormalities. Two foci of restricted diffusion are visualized in the right thalamus and left parietal lobe parenchymal compatible with acute ischemic infarcts. There is associated surrounding increased T2 signal in these regions. There is additional moderate to severe periventricular and subcortical T2/FLAIR signal hyperintensity compatible with moderate small vessel ischemic disease. Evidence of old infarcts are seen in the PICA distribution bilaterally. Diffuse volume loss is also noted. A small right anterior maxillary sinus polyp/mucous retention cyst is visualized.There is no evidence of intracranial hemorrhage or mass. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, remaining paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.No evidence of acute intracranial hemorrhage.2.Small acute ischemic infarcts within the right thalamus and left parietal lobe white matter. No significant mass effect, midline shift or herniation.3.Moderate small vessel ischemic disease.
