Male, 72 years old, with right-sided facial droop and left body weakness. Evaluate for stroke. Restricted diffusion is seen beginning in the right subinsular region and continuing through the corona radiata to reach the right lateral ventricular margin. There is no evidence of significant associated edema or mass effect. No acute intracranial hemorrhage is detected. Mild hemosiderin staining is seen along the right caudate nucleus secondary to chronic ischemia. Moderately extensive patchy periventricular and brainstem T2 hyperintensity is seen compatible with chronic small vessel ischemic disease. Also noted is evidence of a chronic right basal ganglia lacunar infarct. Apart from mild ex vacuo dilatation of the right frontal horn, the ventricular system is within normal limits.
1.Acute ischemia involving the right corona radiata. No significant associated edema, mass effect or acute hemorrhage is observed.2.Moderately extensive sequelae of chronic microvascular ischemic disease and chronic right basal ganglia lacunar infarction are seen.
