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


Infarction of the vermis and the tonsil in the cerebellum presents as truncal and gait ataxia. Acute rotatory vertigo is often present in infarction of the nodulus in the caudal vermis, which is closely associated with the vestibular pathway, but is minor in infarction of the rostral vermis. The rostral vermis receives input from the dorsal spinocerebellar tract (DSCT) which conveys unconsciousness proprioceptive signals from the ipsilateral lower trunk and leg. The present study investigated the characteristics of infarction of the vermis and the tonsil.
