A 67 year-old woman developed a small infarct in the superficial anterior territory of the left middle cerebral artery, then 2 other successive infarcts in the left then right thalamic paramedian territories. Left thalamic infarct was associated with right hemiparesis and speech disorders of the subcortical type. The occurrence of the additional right thalamic infarct was associated with stupor, left hemiparesis and oppositional behavior. A severe blepharospasm and paralysis of convergence and vertical eye movements were also noted. Blepharospasm has been rarely reported with structural central nervous system lesions. An extensive literature review disclosed 2 other cases associated with thalamic paramedian infarcts and 2 additional cases described with other thalamic lesions. In all these cases, blepharospasm seems to have been due to lesions of the intralaminar and dorsomedian nuclei.
一名67岁女性在左大脑中动脉浅前区出现一个小梗死灶，随后在左、右丘脑旁正中区域又相继出现另外2个梗死灶。左侧丘脑梗死伴有右侧偏瘫和皮质下型言语障碍。额外出现的右侧丘脑梗死与木僵、左侧偏瘫及对立行为有关。还发现有严重的眼睑痉挛以及集合和垂直眼球运动麻痹。眼睑痉挛在结构性中枢神经系统病变中很少有报道。广泛的文献回顾发现另外2例与丘脑旁正中梗死有关，还有2例描述的是其他丘脑病变。在所有这些病例中，眼睑痉挛似乎是由于板内核和背内侧核的病变所致。
