Unilateral neglect is usually caused by lesions of the right cerebral cortex, especially parietal. Neglect after subcortical lesions has been reported rarely in thalamic or striatal hemorrhage, and after infarction of thalamus or striatum and internal capsule shown by CT. In these patients, there may have been compression or ischemia of overlying cerebral cortex and white matter. We report a patient with sensory hemineglect, asomatognosia, and anosognosia caused by infarction of striatum and deep white matter, with involvement of neither cortex nor thalamus and without mass effect. This is the first autopsy-confirmed example of human neglect with involvement of only the striatum and deep white matter.
单侧忽视通常由右侧大脑皮质病变引起，尤其是顶叶。丘脑或纹状体出血等皮质下病变后出现的忽视情况鲜有报道，CT显示丘脑、纹状体及内囊梗死之后出现忽视的情况也很少见。在这些患者中，可能存在覆盖其上的大脑皮质和白质受压或缺血的情况。我们报告了一名因纹状体和深部白质梗死导致感觉性偏侧忽视、自体失认症和疾病感缺失的患者，其皮质和丘脑均未受累，也无占位效应。这是首例经尸检证实仅累及纹状体和深部白质的人类忽视病例。
