1928年Bailey.Cushing 和Eisenhardt 证实成血管脑膜瘤是在脑膜新生物中的一组血管性肿瘤。这种解剖-病理学解释引起强烈争议,而很多作者提出血管性脑膜肉瘤或血管外皮细胞瘤显然应同成血管脑膜瘤分开。真正的脑膜肉瘤、血管外皮细胞瘤由不典型或分裂型外皮细胞构成,在基质内呈片状或短束状排列,而基质内有正常结构的丰富毛细血管。作者观察了4例分别是:1.眶部病变;2.幕上 1928 Bailey.Cushing and Eisenhardt confirmed that angiogenic meningiomas are a group of vascular tumors in meningeal neoplasms. This anatomical-pathological explanation is of great controversy, and many authors have suggested that vascular meningioma or hemangiopericytoma should apparently be separated from angiogenic meningioma. Real meningeal sarcoma, hemangiopericytoma by the atypical or split-type epithelial cells in the matrix was flaky or short bundle-like arrangement, and the matrix has a normal structure of abundant capillaries. The authors observed four cases were: 1. Orbital lesions; 2. Curtain
