Ataxia. Subacute cerebellar degeneration. There is redemonstration of substantial disproportionate diffuse cerebellar volume loss and scattered areas of mild T2 hyperintensity. There are also a few unchanged nonspecific foci of T2 hyperintensity in the cerebral white matter. The brainstem and supratentorial structures are otherwise unremarkable. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
No significant interval change in the findings related to cerebellar degeneration.
