目的 总结颅内肿瘤发病规律,探索其流行病学特点,以期增加术前诊断的准确性。方法从年龄、性别、肿瘤发生部位及组织病理学特征等方面,对1988～2000年经手术后病理学检查证实的3740例颅内肿瘤患者进行回顾性分析。结果 颅内肿瘤高发年龄段为31～50岁,男性略多于女性。肿瘤发生部位以幕上最为多见,约占总病例数的79.87％(2987/3740)。组织病理学类型依次为神经上皮肿瘤(32.01％)、脑膜瘤(22.06％)、垂体腺瘤(18.40％)、转移瘤(6.63％)及其他各类肿瘤,其中垂体腺瘤和蛛网膜囊肿的发病率高于文献报道。结论 颅内肿瘤在发病年龄、性别以及肿瘤病理分型、部位等方面均有规律性可循。随着影像学和神经科学的不断发展,颅内肿瘤的病理学分类统计资料有所不同。
Objective To summarize the incidence of intracranial tumors and explore its epidemiological characteristics in order to increase the accuracy of preoperative diagnosis. Methods A retrospective analysis of 3740 patients with intracranial tumors confirmed by postoperative pathology from 1988 to 2000 was conducted from the aspects of age, sex, tumor location and histopathological features. Results The high incidence of intracranial tumors of 31 to 50 years of age, slightly more men than women. The site of tumor was the most common on the screen, accounting for 79.87% (2987/3740) of the total number of cases. Histopathological types were neuroepithelial neoplasia (32.01%), meningioma (22.06%), pituitary adenoma (18.40%), metastatic tumor (6.63%) and other types of tumors, including pituitary adenomas and arachnoid cysts The incidence rate higher than reported in the literature. Conclusion Intracranial tumors in the incidence of age, gender and tumor pathological type, location and other aspects of the regularity to follow. With the continuous development of imaging and neuroscience, pathological classification of intracranial tumors statistics vary.
