Lobule VIIAf (Crus I)

  • Location: Spans entire cerebellum except for a few slices around the midsagittal
  • Description: It is best to initially identify from the most lateral edges and the most posterior axial slice.
    • Notice how this lobule is not in the midsagittal slice.
  • This lobule can also be identified in the sagittal plane as the lobule that is not present at the mid-line but becomes easily discernible roughly 15 mm from the mid-line. It is usually one branch at first that may become two or more at the lateral edges. It should dominate the lateral portion of the cerebellum.
