A woman was referred to the clinic by another neurologist, for long-term followup. She had underwent removal of a tumor in the remote past from her cerebellum. Records are presently not available concerning the type of mass that was removed.

Images below document a large cavity occuping the midline vermis.

On examination, she had slurred speech and imbalance, but was otherwise normal. Careful clinical testing for the usual oculomotor cerebellar signs was negative - -there was no rebound nystagmus, saccadic dysmetria or positional nystagmus.

Comment: After long periods of time, people can adjust and compensate for very substantial amounts of vermal damage.
