【摘要】：正脑膜瘤是起源于蛛网膜脑膜上皮细胞(meningothelial cells)的颅内和椎管内肿瘤,是中枢神经系统最常见的原发性肿瘤之一,占颅内原发肿瘤的13%~26%,仅次于胶质瘤~([1])。绝大部分脑膜瘤是世界卫生组织(World Health Organization,WHO)Ⅰ级良性肿瘤,生长缓慢,手术完全切除后不易复发,预后良好。20%~25%脑膜瘤为Ⅱ级非典型性肿瘤,1%~6%为Ⅲ级恶性肿瘤,这些类型脑膜瘤具有较强的侵袭能力,生长迅速,术后易复发。因此,组
[Abstract]:Meningiomas are intracranial and intraspinal tumors originating from arachnoid epithelial cells (meningothelial cells). They are one of the most common primary tumors in the central nervous system, accounting for 13% ~ (26%) of the primary intracranial tumors, second only to gliomas (~ (1). Most meningiomas are grade I benign tumors of the World Health Organization (World Health Organization,WHO), which grow slowly and are not easy to recur after complete resection. The prognosis of meningiomas is good. 20% ~ 25% meningiomas are grade 鈪，
