Male, 64 years old, with right-sided ataxia, weakness, nystagmus. An moderately sized region of restricted diffusion is seen affecting the inferior right cerebellum. Scattered foci of susceptibility are also seen in this region potentially indicating petechial blood product. Scattered small areas of restricted diffusion are also seen affecting the right lateral medulla, and more superiorly in the right cerebellum. Punctate foci of restricted diffusion are also seen at two sites in the right parietal lobe. There may be be a punctate focus of mild diffusion restriction within the left thalamus but this is equivocal.Scattered foci of FLAIR hyperintensity are seen within the cerebral hemispheres. No evidence of significant generalized mass effect seen. No abnormal extra-axial fluid collections are detected. The ventricles remain normal in size and morphology.
1.Moderately sized acute infarct of the right inferior cerebellum. Scattered foci of susceptibility in this area potentially indicate petechial blood product.2.Additional foci of restricted diffusion are seen within the right lateral medulla, more superiorly in the right cerebellum, and minimally in the right parietal lobe. A faint focus of possible diffusion restriction is seen in the left thalamus but this is questionable at best.3.No significant generalized mass effect is seen. No other areas of suspected intracranial hemorrhage are noted.
