Meningiomas and unruptured cerebral aneurysms (UCAs) rarely coexist. However, the treatment strategy remains to be fully elucidated. This report is a first report that UCA related to the tumor feeder intraoperatively ruptured when the meningioma was resected.
Herein, we present a case of meningioma coexisting with contralateral UCA related to a tumor feeder. Immediately after the meningioma was resected, intraoperative acute brain swelling due to rupture of the contralateral aneurysm appeared. The swollen brain protruding into the epidural space was resected, following contralateral ruptured aneurysm was performed by endovascular surgery. Intensive neurological treatment was administered and the patient gradually recovered.
This report highlights the possibility of intraoperative UCA rupture related to the tumor feeder when the meningioma is resected.
脑膜瘤和未破裂的脑动脉瘤（UCAs）很少同时存在。然而，其治疗策略仍有待充分阐明。本报告首次报道了在切除脑膜瘤时与肿瘤供血相关的 UCA 术中破裂的情况。
本文报告了一例脑膜瘤合并对侧与肿瘤供血相关的 UCA 的病例。脑膜瘤切除后即刻出现对侧动脉瘤破裂引起的术中急性脑肿胀。切除突入硬脑膜外腔的肿胀脑组织，随后通过血管内手术对破裂的对侧动脉瘤进行治疗。给予强化神经治疗后，患者逐渐恢复。
本报告强调了在切除脑膜瘤时与肿瘤供血相关的 UCA 术中破裂的可能性。
