Dystonia and tremor secondary to thalamic infarction successfully treated with thalamotomy of the ventralis intermedius nucleus.

Background: Focal thalamic lesions have been associated with a variety of involuntary movements such as tremor, dystonia, and chorea-ballism.

Methods: We describe a patient with severe hyperkinesias of the right arm secondary to a thalamic infarction in the left postero-ventral region of the thalamus.

Results: The dystonia and tremor of the right upper limb were subsequently controlled with another surgical lesion of the ventralis intermedius nucleus of the thalamus.
