Altered mental status. Assess for stroke. The study is limited by patient motion.There is no diffusion restriction to indicate a recent infarct. There is inflammation related to the chronic right temporal infarct. Addition, there is extensive confluent periventricular cerebral white-matter T2 hyperintensity reflecting chronic microvascular ischemia. Focal volume loss and increased T2 signal involving the posterior-superior aspect of the right cerebellar hemisphere is probably related to chronic right superior cerebellar artery infarct. There is no gross parenchymal hemorrhage though the study is limited by motion.Posterior right lateral ventricular ex vacuo dilatation is superimposed on diffuse dilatation of the ventricular system and the other CSF-containing spaces reflecting moderate to severe volume loss.There is minimal fluid in the mastoid air cells and minimal mucosal thickening in the paranasal sinuses. The orbits show no gross abnormality.
1.Study is limited by patient motion. 2.No evidence of acute intracranial hemorrhage, mass, or acute infarct.3.Moderate cerebral volume loss and chronic right temporal and cerebellar infarcts are present, as described above and on the previous CT scan report.
