Two patients with unilateral spatial neglect caused by right frontal lobe lesions underwent cerebral blood flow studies. A 54-year-old, right-handed woman developed left hemiplegia and frontal lobe neglect associated with cerebral haemorrhage after surgical excision of a frontal tumour. A 66-year-old, right-handed woman developed a haemorrhage in the right frontal lobe caused by rupture of an aneurysm. This was followed by left hemiplegia and frontal lobe neglect. In both cases, 123I-iodoamphetamine single photon emission CT disclosed a reduction in regional cerebral blood flow localised along the circumference of the haematoma in the frontal lobe, but did not reveal any lesions in the parieto-occipital junction. These findings suggest that, in these two cases, the frontal lobe neglect was caused by lesions confined to the frontal lobe.
两名因右侧额叶病变导致单侧空间忽视的患者接受了脑血流研究。一名54岁的右利手女性在额叶肿瘤手术切除后出现脑出血，继而发生左偏瘫和额叶忽视。一名66岁的右利手女性因动脉瘤破裂导致右侧额叶出血，随后出现左偏瘫和额叶忽视。在这两个病例中，123I-碘安非他明单光子发射计算机断层扫描显示额叶血肿周边区域的脑血流量减少，但在顶枕交界处未发现任何病变。这些发现表明，在这两个病例中，额叶忽视是由局限于额叶的病变引起的。
