We report the case of a 47-year-old man with an aneurysm of the anterior cerebral artery revealed by lateral homonymous hemianopic non congruent scotoma. The aneurysm was successfully treated with interventional radiology procedures. In 10p. cent of cases, intracranial aneurysms present prior to their rupture with headache or neuro-ophthalmological symptoms and signs. Isolated visual field defects are rare, and isolated compression of the optic tract is extremely unusual. Although rare, the development of a non-congruent controlateral homonymous hemianopic scotoma is highly suggestive of optic tract compression, and can be explained by the somatotopy of the fibers within the optic tract.
我们报告了一例47岁男性，其大脑前动脉动脉瘤由同侧偏盲性非一致性暗点揭示。该动脉瘤通过介入放射学程序成功治疗。在10%的病例中，颅内动脉瘤在破裂前出现头痛或神经眼科症状和体征。孤立的视野缺损很少见，而对视束的孤立压迫极为罕见。尽管罕见，但非一致性对侧同侧偏盲性暗点的出现强烈提示视束受压，这可以通过视束内纤维的躯体定位来解释。
