Stroke: right upper extremity ataxia. There is restricted diffusion and high T2 signal involving the left parietal and occipital lobes over an area of up to 5 cm with a small amount of petechial hemorrhages, but no large hemorrhagic transformation or midline shift. There also appear to be additional punctate foci of restricted diffusion and in the left subinsular region and inferior left frontal gyrus. The cerebellum is unremarkable. The ventricles and basal cisterns are normal in size and configuration. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a small left maxillary sinus retention cyst. There is a small amount of fluid within the right mastoid air cells.
Recent infarction involving the left parietal and occipital lobes over an area of up to 5 cm with a small amount of petechial hemorrhage, but no large hemorrhagic transformation or midline shift. There also appear to be punctate recent infarcts in the left subinsular region and inferior left frontal gyrus.
