本文报道颅内脑膜瘤1999例,男性占44.6％、女性占55.4％,平均年龄43±13岁,主要发生在大脑凸面、矢状窦旁、大脑镰旁、蝶骨嵴等部位。后期的1313例脑膜瘤中良性占87.6％、恶性占12.4％,良性脑膜瘤中内皮型占53.8％,纤维型占32.0％,过渡型6.8％、混合型0.8％,分型不详6.6％。天幕上的脑膜瘤以内皮型多见,天幕和后颅窝脑膜瘤以纤维型多见;恶性脑膜瘤中血管母细胞型占73.8％。脑膜肉瘤和良性脑膜瘤恶性变者占26.2％。恶性脑膜瘤好发于矢状窦旁、大脑镰旁、中颅窝和天幕,其发生率男性高于女性。
1999 cases of intracranial meningiomas werereported. They located most frequently in cerebralconvexity, parasagittal, falcial, sphenoid ridge re-gions, etc. Among these cases, 44.6% were malesand 55.4% females. The average age at admissionwas 43±13 years. 686 cases which were treatedbefore 1975 had been reported previously. Of therecent 1313 meningioma cases, 87. 6% were benignand 12. 4% were malignant. Of the benign menin-giomas, 53. 8% were meningotheliomatous, 32.0% fibroblastic, 6. 8% transitional, 0. 8% mixedand 6. 6% unclassified. Meningiomas located above tentorium were mostly meningnothelimatous andthose located at tentorial and posterior fossa weremainly fibroblastic forms. Of the malignant menin-giomas, 73.8% were angioblastic forms and 26.2% were meningosarcomas and malignant changefrom benign forms. Malignant meningiomas oc-curred more in males than in females, and they alsolocated mostly in parasagittal, falcial, tentorial, andmiddle fossa.
