Less than one in 1000 meningiomas metastasizes. Although the angioblastic and hemangiopericytic tumors are believed by some authors to metastasize with a greater frequency than the other histologic forms of meningioma, most investigators believe that neither the histologic pattern, local aggressiveness, size, nor location of the tumor can be used accurately to predict which tumors will metastasize. Three new cases are presented, bringing the total reported number of metastasizing meningiomas to 113. If the angioblastic meningiomas and hemangiopericytomas are eliminated from this group, 69 reported cases of "benign" metastasizing meningioma remain.
每1000例脑膜瘤中转移的病例不到1例。尽管一些作者认为血管母细胞性和血管外皮细胞瘤比其他组织学类型的脑膜瘤转移频率更高,但大多数研究者认为,肿瘤的组织学模式、局部侵袭性、大小或位置都不能准确用于预测哪些肿瘤会发生转移。本文报告了3例新病例,使已报告的转移性脑膜瘤总数达到113例。如果将血管母细胞性脑膜瘤和血管外皮细胞瘤排除在该组之外,仍有69例报告的“良性”转移性脑膜瘤病例。
