A left-handed patient was studied who had the acute onset of alexia without agraphia, a left homonymous hemianopia, and prosopagnosia. Neurodiagnostic tests including computerized axial tomography and angiography disclosed bilateral lesions in the posterior cerebral hemispheres involving the splenium of the corpus callosum. Neuropsychologic examination indicated marked impairment of facial discrimination, deficient naming and memory of presented visual material, and mild visual agnosia with relative preservation of other cognitive functions. These findings are consistent with a double disconnection syndrome involving disconnection of the dominant angular gyrus and right inferotemporal cortex from their bilateral visual inputs.
对一名左利手患者进行了研究，该患者突发失读症但无失写症、左侧同向性偏盲和面孔失认症。包括计算机断层扫描和血管造影在内的神经诊断测试显示双侧大脑后半球病变，累及胼胝体压部。神经心理学检查表明面部识别明显受损，对呈现的视觉材料命名和记忆不足，以及轻度视觉失认症，而其他认知功能相对保留。这些发现与一种双重分离综合征一致，该综合征涉及优势角回和右侧颞下皮质与其双侧视觉输入的分离。
