Deep brain stimulation of the thalamic ventral intermediate nucleus for Benedikt's syndrome mainly present as tremor: a long-term case observation

摘要

Benedikt's syndrome (BS) is caused by the lesion in the midbrain and specifically manifests a series of symptoms, including ipsilateral third nerve palsy, contralateral tremor, hemiataxia, and hyperactive tendon reflexes. Deep brain stimulation (DBS) for BS emerges as a new approach and achieves successfully results. We report a successful case report of thalamic ventral intermediate (VIM) nucleus DBS for a patient with BS. During follow-up of 3 years, DBS successfully control the tremor and greatly improve his living and working quality. We consider that VIM DBS may have sustained benefit for refractory BS that mainly presents as tremor.
