Abstract：
Unruptured giant intracranial aneurysms (GIAs) are characterized by their size, which exceeds 25 mm, and these conditions account for approximately 5% of all aneurysm cases. Furthermore, it typically develops in women during the fifth to seventh decade of life. Compared to small aneurysms, which cause subarachnoid hemorrhage, GIAs can manifest as masses or ischemic effects caused by thromboembolism. An elderly female patient, aged 67, was admitted to the hospital with a primary complaint of sudden facial sensory loss on the left side and vomiting. There was also a history of double vision accompanied by left ocular movement disturbance and gradually developed localized headache on the left side. Furthermore, a contrast head magnetic resonance angiography (MRA) revealed the presence of a high-flow giant aneurysm, measuring 30.7 × 31.8 × 27.2 mm in the cavernous segment of the left internal carotid artery (ICA). Cerebral angiography showed the absence of flow on the left ICA due to total occlusion. After cerebral angiography, the patient remained conscious but exhibited some neurological deficits, which were identical to the initial symptoms observed during hospitalization. Cases of spontaneous thrombosis in GIA are extremely rare. However, radiological examination, particularly angiography, can be used to diagnose spontaneous thrombosis in unruptured GIAs to ensure that the patient receives the right treatment.
摘要：
未破裂的巨大颅内动脉瘤（GIA）的特征在于它们的大小，超过25毫米，这些疾病约占所有动脉瘤病例的5%。此外，它通常在女性生命的第五到第七个十年中发展。与小动脉瘤相比，导致蛛网膜下腔出血,GIA可以表现为由血栓栓塞引起的肿块或缺血效应。一位老年女性患者，67岁，入院，主要主诉左侧突然面部感觉丧失和呕吐。也有复视史，伴有左眼运动障碍，并逐渐发展为左侧局限性头痛。此外，对比头磁共振血管造影（MRA）显示存在高流量的巨大动脉瘤，测量左侧颈内动脉（ICA）海绵窦段30.7×31.8×27.2mm。脑血管造影显示，由于完全闭塞，左侧ICA上没有血流。脑血管造影后,病人保持清醒，但表现出一些神经缺陷，与住院期间观察到的初始症状相同。GIA中自发性血栓形成的病例极为罕见。然而,放射学检查,特别是血管造影，可用于诊断未破裂GIA的自发性血栓形成，以确保患者接受正确的治疗。
