Abstract：
A 56-year-old right-handed man was referred to our hospital for evaluation of sudden-onset transient quadrantanopia, which was followed by throbbing headache consistent with migraine with aura (MA). Magnetic resonance imaging (MRI) of the right parieto-occipital cortex on admission showed a hyperintense region on diffusion-weighted imaging, which disappeared 7 days later. A small cortical infarct in the parieto-occipital cortex can cause MA-like headache, and the present infarct lesion was only detectable on MRI during the acute phase. Performing MRI for patients with suspected acute MA might help identify the cause of MA-like headache and ensure appropriate management of patients.
摘要：
一名56岁的右撇子被转诊到我们医院评估突发性短暂性正交视，其次是与先兆偏头痛（MA）一致的抽动性头痛。入院时右侧顶枕叶皮质的磁共振成像（MRI）在弥散加权成像上显示出高强度区域，7天后消失了。顶枕骨皮质的小皮质梗塞可引起MA样头痛，而目前的梗死灶只能在急性期MRI上检测到。对疑似急性MA的患者进行MRI可能有助于确定MA样头痛的原因并确保对患者进行适当的管理。
