A 74-year-old man with vasculopathic risk factors presented to the emergency room with a chief complaint of peripheral vision loss resulting from an intracranial hemorrhage in his right parietal and occipital lobes. Urgent craniotomy and ventriculostomy led to a stable clinical condition with subsequent development of a crossed quadrant homonymous hemianopsia (checkerboard visual field) due to a new right parieto-occipital infarct superimposed on a prior left occipital infarct. This uncommon visual field defect represents juxtaposed homonymous quadrantanopias that produce a striking checkerboard appearance that is almost pathognomonic for bilateral occipital lesions.
一位 74 岁的男性，有血管病变风险因素，因右侧顶叶和枕叶的颅内出血到急诊就诊，主要抱怨视野缺失。紧急开颅术和脑室造口术使病情稳定，随后由于新的右顶枕叶梗死叠加在先前的左枕叶梗死上，出现了交叉象限同向偏盲（棋盘状视野）。这种不常见的视野缺损代表了毗邻的同象限偏盲，产生了引人注目的棋盘状外观，几乎是双侧枕叶病变的特征性表现。
