Background: 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. Patients and Methods: Neuroradiological findings of 3 patients whose lesions were located in the vermis or the tonsil were analyzed. Results: All lesions were located in the anterior lobe in the rostral vermis, the nodulus in the caudal vermis, or the tonsil. Truncal and gait ataxia were exhibited by 3 patients. Rotatory vertigo was exhibited by 2 patients whose lesions were located in the nodulus and the tonsil, but absent in a patient with infarction of the anterior lobe. Lateropulsion opposite the lesion was apparent in a patient with infarction of the tonsil. Gaze-evoked nystagmus was observed in 2 patients with infarction of the nodulus and the tonsil. Conclusions: 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.
