To describe a rare presentation of vertebral artery dissection (VAD) as a small but congruous incomplete homonymous hemianopia demonstrating use of visual field testing in the diagnosis.
A 30 year old woman had been unwell for 4 months with difficulty focusing, vertigo, dizziness and a feeling of falling to the right. A small but congruous right inferior homonymous quadrantanopia was found on examination leading to further investigation that uncovered a vertebral artery dissection and multiple posterior circulation infarctions including a left occipital stroke matching the field defect.
We describe an atypical case of VAD presenting with a small congruous quadrantanopia. This is a rare but significant condition that predisposes to multiple thromboembolic infarction that may be easily misdiagnosed and a high index of suspicion is required to make the diagnosis.
描述一种罕见的椎动脉夹层（VAD）表现为小但一致的不完全同向偏盲，展示了视野检查在诊断中的应用。
一名 30 岁女性，持续 4 个月出现难以集中注意力、眩晕、头晕和向右侧摔倒的感觉。检查发现右侧下象限同向偏盲较小但一致，进一步检查发现椎动脉夹层和多个后循环梗死，包括与视野缺陷相匹配的左侧枕叶中风。
我们描述了一例不典型的 VAD 病例，表现为小的一致象限偏盲。这是一种罕见但重要的情况，易导致多发血栓栓塞性梗死，可能容易误诊，需要高度怀疑以做出诊断。
