Infarcts involving the thalamus can yield many deficits, including sensory syndromes, altered consciousness, and cognitive disturbances, depending on the thalamic vascular territory involved. Isolated truncal contrapulsion due to pure thalamic infarct has been rarely reported. Truncal lateropulsion is a compelling sensation of being pulled toward one side that cannot be explained by weakness or limb ataxia. It is commonly reported in lateral medullary infarcts. It may occur with lesions that involve the peripheral vestibular system, brainstem, cerebellum, basal ganglia, ponto-mesencephalic, and thalamic lesions. We hereby report a 64-year-old woman who presented with truncal contrapulsion as the sole manifestation of an acute right lateral thalamic infarct.
根据所累及的丘脑血管区域，累及丘脑的梗死可导致多种功能缺损，包括感觉综合征、意识改变和认知障碍。因单纯丘脑梗死导致的孤立性躯干对侧推挤很少见报道。躯干侧方推挤是一种被拉向一侧的强烈感觉，无法用无力或肢体共济失调来解释。它常见于延髓外侧梗死。它可能与累及外周前庭系统、脑干、小脑、基底神经节、脑桥中脑以及丘脑的病变有关。我们在此报告一名64岁女性，其以躯干对侧推挤作为急性右侧丘脑梗死的唯一表现。
