Axial views reveal that supra tentorially there is normal gyral and sulcal appearance for the patients age with no demonstrable evidence of significant atrophy of the gyrus.
However infra tentorially the cerebellum is symmetrically atrophic.
The folia are significantly atrophic and shrunken with too much spacing between the folia. Additionally, the inter-fissure distance between all fissures is increased.
These atrophic changes are symmetrical, in keeping with the symmetrical cerebellar signs, and out of keeping for the patients age.
