目的：探讨颅内脑膜瘤的临床病理联系。方法：对640例颅内脑膜瘤病例重新观察并进行统计分析。结果：女性脑膜瘤病人明显高于男性（P＜0．01），主要发病部位是幕上（89．2％），病理组织学类型主要为脑膜上皮型（50．3％）、纤维型（28．5％）和移行型（10．3％）。脑膜瘤的复发率为7.5％。结论：脑膜瘤是颅内第二常见肿瘤，容易复发，复发性脑膜瘤中，恶性脑膜瘤的发生率明显高于初发性脑膜瘤。
Objective: To investigate the clinicopathological relationship of intracranial meningiomas. Methods: 640 cases of intracranial meningioma were re-observed and analyzed statistically. Results: The incidence of female meningioma was significantly higher than that of male (P <0.01). The main site of disease was supratentorial (89.2%). The main pathological types were meningioepithelium (50.3%), fibrous 28.5%) and migratory (10.3%). The recurrence rate of meningioma was 7.5%. Conclusion: Meningioma is the second most common intracranial tumor, which is easy to relapse. The incidence of malignant meningioma in recurrent meningioma is significantly higher than that of primary meningioma.
