Disappearance of resting tremor after thalamic stroke involving the territory of the tuberothalamic artery.

Disappearance of resting tremor was observed in a 76-year-old patient with Parkinson's disease after a contralateral thalamic infarct involving the territory of the tuberothalamic artery. Based on the analysis of surgical data of Parkinson's disease patients, this might be explained by the lesion of the ventral lateral nucleus, which is supplied by the inferolateral and tuberothalamic arteries. Thalamic infarction in the territory of the tuberothalamic artery as well as the inferolateral artery can produce amelioration of tremor.
