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.

顶枕叶皮层小梗塞诱发的偏头痛样先兆头痛：病例报告。

一名 56 岁的右撇子男子因突发性一过性象限视力障碍转诊至我院，随后出现与先兆偏头痛（MA）一致的搏动性头痛。入院时右侧顶枕皮层的磁共振成像（MRI）显示，弥散加权成像上有一个高强度区域，7 天后该区域消失。顶枕叶皮质的小皮质梗死可导致 MA 样头痛，而目前的梗死病灶只有在急性期才能在核磁共振成像中发现。对疑似急性MA患者进行磁共振成像检查有助于确定MA样头痛的病因，确保对患者进行适当的治疗。
