Female, 66 years old, with acute onset altered mental status, right gaze preference and left-sided weakness. Image quality is significantly degraded by motion artifact. On the left, multiple scattered small foci of restricted diffusion are seen within the bilateral cerebral hemispheres, predominantly in the watershed zones. There is evidence of moderately extensive patchy periventricular and subcortical T2 hyperintensity. Also noted is a probable chronic left parietal infarct. No large fluid collections are suspected. The ventricles are normal in size and morphology.
1.Multiple scattered small foci of acute ischemia are seen in the bilateral cerebral hemispheres, likely watershed in nature.2.Evidence of chronic microvascular ischemic disease and a chronic left parietal infarct is also seen.3.Please note that due to image degradation, subtle lesions may not be detected.
