BACKGROUND
Worldwide there are varying reports on the prevalence of meningiomas among intracranial neoplasms. Different reports state intracranial meningiomas, gliomas or metastatic tumours as the most common tumour among intracranial neoplasms. We present our institutions' experience of patients with intracranial neoplasms and a comparison of our findings with those from the literature.
OBJECTIVE
To determine the relative frequency of intracranial meningiomas among intracranial neoplasms in our environment.
METHODS
Consecutive patients (151) seen at the CMJAH and CHBAH, Johannesburg, with histologically proven intracranial neoplasms over a 12 month period were analyzed.
RESULTS
The commonest histological types were meningiomas, gliomas and pituitary tumours. Forty eight (31.8%) patients had histologically confirmed intracranial meningiomas during the study period, 35 (23.2%) had pituitary adenomas and 32 (21.2%) had gliomas. The mean age of the patients was 43 years with a female-to-male ratio of 1.3:1. The peak age range at presentation was in the fifth (27.1%) and sixth (26.5%) decades.
CONCLUSION
The study showed that meningioma is the most common tumour among intracranial neoplasms in our environment.
背景
关于颅内肿瘤中脑膜瘤的患病率，全球有不同的报道。不同报道称颅内脑膜瘤、胶质瘤或转移性肿瘤是颅内肿瘤中最常见的肿瘤。我们介绍了我们机构颅内肿瘤患者的情况，并将我们的研究结果与文献中的结果进行了比较。
目的
确定在我们所处环境中颅内肿瘤中颅内脑膜瘤的相对发生率。
方法
对在约翰内斯堡的CMJAH和CHBAH连续就诊的151例患者进行分析，这些患者在12个月期间经组织学证实患有颅内肿瘤。
结果
最常见的组织学类型是脑膜瘤、胶质瘤和垂体肿瘤。在研究期间，48例（31.8%）患者经组织学证实患有颅内脑膜瘤，35例（23.2%）患有垂体腺瘤，32例（21.2%）患有胶质瘤。患者的平均年龄为43岁，女性与男性的比例为1.3:1。就诊时的年龄高峰在第五个十年（27.1%）和第六个十年（26.5%）。
结论
该研究表明，在我们所处环境中，脑膜瘤是颅内肿瘤中最常见的肿瘤。
