Migrainous infarction accounts for 12.8% of ischemic strokes of unusual etiology.
A 59-year-old woman with longstanding migraine with aura experienced what appeared to be migrainous infarction characterized by dysmetropsia and transient Cotard's syndrome. Imaging demonstrated right temporal-parietal-occipital changes with apparent cortical laminar necrosis.
The spectrum of the pathophysiology of migrainous infarction has not been established; however, cortical spreading depression may explain the appearance of imaging findings that do not obey a vascular territory.
偏头痛性梗死占病因不明的缺血性卒中的12.8%。
一名患有长期伴有先兆偏头痛的59岁女性经历了一次疑似偏头痛性梗死，其特征为视物显大症和短暂的科塔尔综合征。影像学检查显示右侧颞顶枕叶改变，伴有明显的皮质层状坏死。
偏头痛性梗死的病理生理谱尚未明确；然而，皮质扩散抑制可能解释不符合血管分布区域的影像学表现。
