Male, 68 years old, with gait imbalance. Assess for cerebellar etiology. The cerebellum is normally formed and shows preserved parenchymal volume. No abnormal signal or pathologic enhancement is demonstrated in the posterior fossa.Supratentorially, mild diffuse prominence of the sulci is seen compatible with parenchymal volume loss. A single nonspecific focus of T2 hyperintensity is evident within the right frontal white matter.No evidence of parenchymal edema, mass effect or pathologic enhancement is seen. No abnormal extra-axial fluid collections are detected. The ventricular system is within normal limits for size and morphology. The corpus callosum is rather undulating in contour as viewed in the sagittal plane and thins at the junction of the body and splenium, but this can be developmental and is of doubtful significance.
1.No specific findings are seen to account for the patient's gait abnormality. In particular, the cerebellum is within normal limits.2.Mild supratentorial parenchymal volume loss and a nonspecific focus of right frontal white matter signal abnormality are noted incidentally.
