Bálint syndrome (simultagnosia, optic ataxia, and ocular apraxia) is typically caused by pathology affecting the parietal-occipital regions bilaterally. Visual allochiria is an uncommonly reported symptom associated with parietal lobe pathology in which visual stimuli presented to one hemispace are transposed to the opposite side. We describe a patient with Bálint syndrome and visual allochiria whose initial brain MRI demonstrated acute infarction of the right parietal-occipital region. Repeat imaging 9 days later revealed bilateral parietal-occipital infarctions consistent with the observed clinical syndrome. Reversible cerebral vasoconstriction syndrome is introduced as a novel cerebrovascular etiology of Bálint syndrome.
巴林特综合征（同时失认症、视觉性共济失调和眼球运动不能）通常由双侧顶枕叶病变引起。视觉交叉性忽视是一种少见的与顶叶病变相关的症状，表现为呈现于一侧视野的视觉刺激被错置于对侧。我们描述了一例巴林特综合征伴视觉交叉性忽视患者，其初始脑 MRI 显示右侧顶枕叶急性梗死。9 天后的重复影像学检查显示双侧顶枕叶梗死，与观察到的临床综合征一致。可逆性脑血管收缩综合征被认为是巴林特综合征的一种新的脑血管病因。
