Gait imbalance with veering left greater than right. No restricted diffusion abnormality to suggest acute ischemia. The brain parenchymal signal intensity is within normal limits for age. There is a juxtacortical punctate focus of T2 hyperintensity in the left superior frontal gyrus, which is nonspecific. The ventricles, sulci, and basal cisterns are normal in size and configuration. There is no evidence of regional mass effect or midline shift. The cerebellum is normal in appearance without evidence of atrophy. The cerebellar tonsils are normal in position. No abnormal foci of enhancement are noted. Incidentally noted is a developmental venous anomaly in the right middle frontal gyrus. A focus of susceptibility in the right occipital lobe likely represents old microhemorrhage or mineralization. There is no associated edema. There is patchy paranasal sinus mucosal thickening/opacification involving the ethmoid air cells and maxillary sinuses. The orbits are within normal limits.
No evidence of cerebellar atrophy or other specific findings which would account for the patient's symptoms.
