Male, 67 years old, with known right ICA plaque and area of right-sided ischemia on CT, evaluate for ischemia. Patchy restricted diffusion is seen in the right centrum semiovale, along the right lateral ventricular atrium, within the right occipital lobe, and minimally in the right temporal lobe. These lesions demonstrate correlating T2 hyperintensity. A few additional scattered T2 hyperintense lesions are demonstrated in the cerebral hemispheres which do not show diffusion restriction. Evidence of a small chronic lacunar infarct is seen in the left basal ganglia, along with a small chronic right cerebellar cortical stroke.No evidence of significant generalized mass effect is seen. No acute intracranial hemorrhage or any abnormal extra-axial fluid collections are detected. The ventricles are normal in size and morphology.
1.Scattered areas of acute ischemia are seen within the right cerebral hemisphere, predominantly within the MCA distribution.2.No evidence of significant generalized mass effect is seen. No intracranial hemorrhage is detected.
