A 66-year-old male presented with a sudden severe headache, transient loss of consciousness and persisting vertigo. A subarachnoid hemorrhage was detected via lumbar puncture. The CT scan was negative and an MRI detected a few T2 hyperintense foci of ischemic origin and the suspected subarachnoid hemorrhage. An MRA revealed occlusions of all four magistral cerebral arteries and the presence of an excessively developed collateral circulation, later proven with DSA. The patient did not suffer from focal ischemia despite this severe cerebrovascular disease. At the time of discharge after 30 days of hospitalization, previous mild meningeal signs, cephalea and vertigo were no longer present.
一名66岁男性，突发剧烈头痛、短暂意识丧失并持续眩晕。经腰椎穿刺检测发现蛛网膜下腔出血。CT扫描结果为阴性，而MRI检测到一些缺血性起源的T2高信号病灶以及疑似蛛网膜下腔出血。磁共振血管造影（MRA）显示四条主要脑动脉均有闭塞，且存在过度发育的侧支循环，后来经数字减影血管造影（DSA）证实。尽管患有这种严重的脑血管疾病，但该患者并未出现局灶性缺血症状。住院30天后出院时，先前的轻度脑膜刺激征、头痛和眩晕症状均已消失。
