Disappearance of resting tremor after “stereotaxic” thalamic stroke

Both stereotaxic thalamotomy and deep brain stimulation have been shown to be effective treatment for drug-resistant resting tremor in selected patients.1 The preferred targets of surgical intervention are the thalamic nucleus ventralis intermedius (Vim) and an area a millimeter anterior to the nucleus ventrocaudalis (Vc), which have been associated with relief of tremor with contralateral paresthesia and hypesthesia the commonest side effects.2 We report a patient with Parkinson disease (PD) with disappearance of contralateral resting tremor after a pure sensory stroke involving the posterolateral part of the left thalamus. A 67-year-old man suddenly developed numbness in the right lower lip, the right part of the tongue, and the right hand. He had been followed by our department for PD for 7 years, and initially …
