We evaluated the magnetic resonance images of the patients with intent
ion tremor. Five patients out of seven had some atrophic structures or
changes in signal intensity in the cerebello-rubral thalamic tract. M
oreover, the T-2-weighted images of the patients group detected the de
ntate and red nuclei more poorly than those of our control group. From
these results, the etiological significance of the tract was confirme
d and the mechanism of the intention tremor onset was discussed.
