Abstract
- A 67-year-old man, with a history of pontine hemorrhage, was admitted because of ocular tremors. Also, tremors in the right upper limb and palates were detected. Oculopalatine tremors showed synchronous vertical oscillations and the limb showed midbrain tremor. Brain MRI revealed high signal intensities of both inferior olivary nuclei and right superior cerebellar peduncle. Electromyogram showed different tremor frequencies in the oculopalate and limb. Clinical, MRI and electromyographic findings indicate that the origins of oculopalatine and limb tremors are different.
