Meningiomas are benign tumors arisising from arachnoid cells and represent the commonest asymptomatic intracranial tumors. We analysed 69 supratentorial meningiomas managed by the Neurosurgical Tumor Group of the Clinics Hospital of Medicine School of São Paulo University (September 1995 to September 1997). Age, sex, edema degree, tumor site, surgical complications and mortality were studied. Edema degree was defined by radiological methods (CT and MRI). Forty-seven patients were women and average age was 58 years. Type II of edema degree was predominant (38.7%). Twenty-nine patients had parasagital meningiomas and 40 presented convexity tumors. Simpson I resection was obtained in 48 procedures, II in 18 and III in two surgical removals. Nine cases complicated (transitory deficits, 6; permanent deficit, 1; and infection, 2). Death occurred in two patients. Morbity and mortality had relation with age, falx tumors and attempt of radical surgical removal. Edema degree did not modify mortality and morbidity rates.
脑膜瘤是起源于蛛网膜细胞的良性肿瘤，是最常见的无症状颅内肿瘤。我们分析了圣保罗大学医学院临床医院神经外科肿瘤组在1995年9月至1997年9月期间治疗的69例幕上脑膜瘤。研究了年龄、性别、水肿程度、肿瘤部位、手术并发症和死亡率。水肿程度通过放射学方法（CT和MRI）确定。47例患者为女性，平均年龄58岁。水肿程度II型占主导（38.7%）。29例患者患有矢状窦旁脑膜瘤，40例表现为凸面肿瘤。48例手术切除达到辛普森I级，18例达到II级，2例手术切除达到III级。9例出现并发症（短暂性神经功能缺损6例、永久性神经功能缺损1例、感染2例）。2例患者死亡。发病率和死亡率与年龄、镰旁肿瘤以及根治性手术切除的尝试有关。水肿程度并未改变死亡率和发病率。
