INTRODUCTION
Persistent migraine aura without headache is an extremely rare condition. The International Headache Society defines various subtypes of migraines, including "persistent migraine aura without infarction" and "typical aura without headache."
CASE PRESENTATION
We describe the case of a 21-year-old Asian woman with a history of migraine without aura who had (as her first aura episode) persistent negative visual symptoms without headache for 6 months. We detected no lesions that could cause her persistent visual symptoms. Based on the patient's history of migraine without aura and responsiveness to furosemide and lamotrigine, we concluded that the visual symptoms in this case were related to migraine visual auras.
CONCLUSIONS
Persistent visual aura without headache overlapped the criteria for the two migraine subtypes mentioned above and thus did not fit an exact diagnosis. Therefore, we assert that new criteria are needed to encompass uncertain visual symptoms of migraine aura.
引言
无头痛性持续性偏头痛先兆是一种极为罕见的病症。国际头痛协会对偏头痛的各种亚型进行了定义，包括“无梗死的持续性偏头痛先兆”和“无头痛的典型先兆”。
病例报告
我们描述了一名21岁亚洲女性的病例，她有偏头痛但无先兆病史，此次（首次出现先兆发作）出现无头痛的持续性负面视觉症状，持续了6个月。我们未发现可导致其持续性视觉症状的病变。基于该患者无先兆偏头痛病史以及对呋塞米和拉莫三嗪的反应，我们得出结论，该病例中的视觉症状与偏头痛视觉先兆有关。
结论
无头痛性持续性视觉先兆与上述两种偏头痛亚型的标准重叠，因此不符合确切诊断。所以，我们认为需要新的标准来涵盖偏头痛先兆不确定的视觉症状。
