摘　　要：目的探讨侵袭性脑膜瘤的影像学特点和外科手术治疗特点。方法对手术治疗的125例侵袭性脑膜瘤患者的影像资料进行回顾性分析,肿瘤位于幕上者95例(包括大脑凸面、镰窦旁及侧脑室内,不包含前中颅窝底),颅底者23例(鞍区、前中颅窝底及跨中后颅窝者),幕下者后颅窝者7例。结果 125例患者共进行198次手术,其中1次手术者75例,2次手术者41例,3次手术者9例,15例行放射治疗,30例行伽马刀治疗,首次手术SimpsonⅠ级切除者98例,Ⅱ级切除者20例,Ⅲ级切除者7例,无SimpsonⅣ级切除者。出院后共有90例患者得到5个月以上随访,随访最长时间为5年。结论侵袭性脑膜瘤的最基本治疗方法是手术切除,辅以伽马刀治疗或放疗是延缓肿瘤复发延长患者寿命的重要手段。Objective To study the imaging characteristics and the characteristics of surgical treatment of invasive meningioma. Methods A retrospective analysis was performed on 125 patients with invasive meningiomas. The tumors were located in the supratentorial area of 95 patients（ including the convex side of the brain,the side of the falxus and the lateral ventricle,not including the anterior cranial fossa） 23 cases（ saddle area,before the middle cranial fossa and in the middle of the posterior fossa）,the posterior cranial fossa were 7 cases. Results A total of 198 operations were performed in 125 patients. Among them,75 cases were performed once,41 cases were performed twice,9 cases were performed 3 times,15 cases were treated with radiotherapy,30 cases were treated with gamma knife,the first operation was Simpson Ⅰ Grade resection in 98 cases,Ⅱ resection in 20 cases,Ⅲ resection in 7 cases,no Simpson Ⅳ resection. A total of 90 patients were discharged from hospital after 5 months of follow-up,the longest time of 5 years. Conclusion The most basic treatment of invasive meningioma is surgical resection,combined with gamma knife therapy or radiotherapy is an important means to delay tumor recurrence and prolong life of the patients.
