A 32-year-old woman, who had developed head tremor and paresthesia of the right upper limb for several months, was admitted to our hospital. The diagnosis of multiple sclerosis was made because the serial MRI showed multiple lesions in both the cerebral white matter and the cervical cord. Oligoclonal IgG band was positive. Her symptoms were improved by intravenous methylprednisolone and an antiepileptic drug (MEPM 1 g/day and CZP 1 mg/day). The head tremor was the so-called "yes-yes" type which shakes back and forth. Although this type of tremor has been considered to be developed by the lesions in the cerebellum, our patient seemed to develop the tremor by cervical cord lesion. Further investigation is needed to confirm the association of the head tremor and the cervical lesions in MS.
