A 47-year-old man presented with carotid rete mirabile manifesting as subarachnoid hemorrhage (SAH). Computed tomography showed SAH, and angiography disclosed an abnormal vascular network around the petrous and cavernous portions of the internal carotid artery. Single photon emission computed tomography (SPECT) with technetium-99m methyl cysteinate dimer revealed reduced regional cerebral blood flow (CBF). Twelve months later, he was leading a normal life without neurological problems, hemorrhage, or ischemic manifestations. SPECT with iodine-123 N-isopropyl-p-iodoamphetamine and the acetazolamide challenge test showed the CBF had normalized.
一名47岁男性因表现为蛛网膜下腔出血（SAH）的颈动脉奇异网而就诊。计算机断层扫描显示为SAH，血管造影显示颈内动脉岩骨段和海绵窦段周围存在异常血管网。用锝-99m半胱氨酸二聚体进行的单光子发射计算机断层扫描（SPECT）显示局部脑血流量（CBF）降低。12个月后，他过着正常生活，没有神经问题、出血或缺血表现。用碘-123 N-异丙基-p-碘安非他明进行的SPECT和乙酰唑胺激发试验显示CBF已恢复正常。
