Intellectual impairment, poor articulation, and mild cerebellar ataxia. The images are partly degraded by dental brace artifacts. Nevertheless, there is marled diffuse cerebellar volume loss. The brain stem and supratentorial brain appear unremarkable. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The supratentorial ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact.
Marked diffuse cerebellar volume loss, which may be related to a neurodegenerative process.
