Female, 62 years old, with two days of slurred speech, history of prior stroke. Image quality is reduced by motion artifact on several sequences.A subcentimeter focus of restricted diffusion is seen within the left centrum semiovale just inferior to the precentral gyrus. Very mild restricted diffusion is also seen at the level of the precentral gyrus.In addition to the above lesions, there are a number of scattered small foci of nonspecific white matter T2 hyperintensity. A small chronic infarct of the right cerebellum is also seen.No significant parenchymal edema or mass effect is detected. There is no evidence to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collections. The ventricles are normal in size and morphology.The middle nasal turbinates appear thickened which may represent mucosal edema, secretions or polyps.
1.Foci of acute ischemia are seen within and just inferior to the left precentral gyrus.2.Scattered small foci of T2 hyperintensity are nonspecific but may reflect chronic microvascular ischemic disease. A small chronic infarct of the right cerebellum is seen.3.No evidence of any significant generalized mass effect is detected.
