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.

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.
