Clinical Study on 3 Patients with Infarction of the Vermis/Tonsil in the Cerebellum

The tonsil and the nodulus were considered to have a close relationship with the vestibular pathway. Absence of rotatory vertigo indicated impairment of the DSCT. Our data suggested that the cause of truncal and gait ataxia differed between the rostral vermis and the caudal vermis/tonsil.
