We report two cases of unilateral spatial neglect associated with an isolated right frontal lobe lesion. Case 1 was a 59-year-old, right-handed man, who developed a left hemiplegia, disorientation, and frontal lobe neglect associated with a haemorrhagic contusion following a head injury. Case 2 was a 55-year-old, right-handed man, who also developed disorientation and frontal lobe neglect secondary to a haemorrhagic contusion following a head injury. 99mTc HM-PAO SPECT revealed an isolated reduction in the regional cerebral blood flow (CBF) around the haematoma in the frontal lobe; blood flow to remaining parts of the brain was normal. Damage to the right frontal lobes of these patients was confirmed as being the cause of the unilateral spatial neglect in accordance with the results of CBF studies.
我们报告了两例与孤立性右额叶病变相关的单侧空间忽视病例。病例1是一名59岁的右利手男性，头部受伤后出现左侧偏瘫、定向障碍和与出血性挫伤相关的额叶忽视。病例2是一名55岁的右利手男性，头部受伤后也因出血性挫伤继发出现定向障碍和额叶忽视。99mTc HM-PAO单光子发射计算机断层扫描显示额叶血肿周围局部脑血流量（CBF）单独减少；大脑其余部分的血流正常。根据CBF研究结果，证实这些患者右额叶受损是单侧空间忽视的原因。
