Abstract：
UNASSIGNED: Perianeurysmal cyst formation after endovascular treatment of cerebral aneurysms is a rare complication; however, the number of reports has gradually increased in recent years due to the development of several endovascular treatments.
UNASSIGNED: We present a case of delayed perianeurysmal cyst enlargement 8 years after endovascular treatment for multiple recurrences of a large cerebral aneurysm in the anterior communicating artery. The patient presented with obstructive hydrocephalus caused by an enlarged perianeurysmal cyst. The patient underwent cyst fenestration using neuroendoscopy and ventriculoperitoneal shunting, recovered from the clinical symptoms, and had a good prognosis. Histopathological findings showed that the cyst wall contained a fibrotic layer under the monoependymal layer with hemosiderosis without evidence of neovascularization or inflammatory cell infiltration. These findings suggest that the origin of the perianeurysmal cyst wall is not the aneurysm itself but the adjacent brain tissue.
UNASSIGNED: Perianeurysmal cysts can develop during long-term follow-up, and clinicians should consider surgical treatment, including cyst fenestration, using neuro-endoscopy if the cyst presents with clinical symptoms.

摘要：
■脑动脉瘤血管内治疗后动脉瘤周围囊肿的形成是一种罕见的并发症；然而，近年来，由于几种血管内治疗方法的发展，报道数量逐渐增加。
■我们介绍了一例前交通动脉大型脑动脉瘤多次复发的血管内治疗8年后动脉瘤周围囊肿迟发性扩大的病例。该患者表现为由动脉瘤周围囊肿扩大引起的阻塞性脑积水。患者使用神经内镜和脑室腹膜分流术进行了囊肿开窗术，从临床症状中恢复，预后良好.组织病理学发现表明，囊肿壁在单室膜层下方包含纤维化层，伴有含铁血黄素沉着症，没有新血管形成或炎性细胞浸润的证据。这些发现表明，动脉瘤周围囊肿壁的起源不是动脉瘤本身，而是邻近的脑组织。
■在长期随访期间，动脉瘤周围囊肿可以发展，临床医生应该考虑手术治疗，包括囊肿开窗术,如果囊肿有临床症状，使用神经内镜检查。
