Right-sided weakness with history of previous stroke. Evaluate for stroke. Motion artifact somewhat limits evaluation. There is no evidence of acute infarct. There is encephalomalacia and ex vacuo dilatation of the right lateral ventricle, related to chronic infarct in the right MCA territory involving the right frontal and temporal lobes as well as the insula and basal ganglia. There is hemosiderin staining in the region of the prior right MCA territory infarct. There is no evidence of acute intracranial hemorrhage or mass effect. There are scattered punctate foci of abnormal T2/FLAIR hyperintensity within the periventricular and subcortical white matter, consistent with mild chronic small vessel ischemic changes. There is chronic volume loss in the right cerebral peduncle, likely due to Wallerian degeneration. The ventricles and basal cisterns are unchanged in size and configuration. There is mild mucosal thickening in the small left maxillary sinus. The skull and extracranial soft tissues are unremarkable. There is attenuation of the right middle cerebral artery flow void.
1.No evidence of acute infarct or intracranial mass effect.2.Chronic right MCA territory infarct which has evolved since prior MRI from 3/17/2011. There is associated Wallerian degeneration along the right corticospinal tract.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
