Truncal ataxia from infarction involving the inferior olivary nucleus

J Stroke Cerebrovasc Dis. 2012 Aug;21(6):507-8. doi: 10.1016/j.jstrokecerebrovasdis.2010.11.001. Epub 2011 Jan 31.

Abstract

Truncal ataxia in medullary infarction may be caused by involvement of the lateral part of the medulla; however, truncal ataxia in infarction involving the inferior olivary nucleus (ION) has received comparatively little attention. We report a patient with truncal ataxia due to medial medullary infarction located in the ION. A lesion in the ION could produce a contralateral truncal ataxia due to increased inhibitory input to the contralesional vestibular nucleus from the contralesional flocculus.
