The spectrum of closed head injury ranging from asymptomatic to lethal is well described in the literature. In a small number of cases, dramatic neurologic symptoms normally associated with cerebrovascular accident or vascular headache may arise following apparently insignificant head trauma. We report two cases of young males who developed transient blindness accompanied by significant neurologic abnormality following trivial head injuries. These phenomena are previously well documented, and it is believed that in certain individuals, minor head trauma can induce a type of migraine equivalent known as "footballer's migraine" or "posttraumatic cortical blindness." Current knowledge of these two conditions is reviewed.
文献中对闭合性颅脑损伤从无症状到致命的范围已有详尽描述。在少数情况下，看似微不足道的头部创伤后可能会出现通常与脑血管意外或血管性头痛相关的严重神经系统症状。我们报告了两例年轻男性病例，他们在轻微头部损伤后出现了短暂性失明并伴有明显的神经功能异常。这些现象此前已有充分记载，据信在某些个体中，轻微头部创伤可诱发一种被称为“足球运动员偏头痛”或“创伤后皮质盲”的偏头痛等效症。本文对这两种病症的现有知识进行了综述。
