根据文献中不同材枓的统计,脑瘤约占人体所有肿瘤1.8%;亦有人权据尸体解剖来统计,证实脑居身体各器官肿瘤发病率的第四位。由此可见脑瘤并非一鲜见疾患。由于颅内组织成份甚多、胚胎来源各异,故颅内肿瘤之种类亦甚多。通常临床上所指之范围包括如下:1.来自神经组织者:如胶质瘤(胶质母细胞瘤、星状细胞瘤、髓母细胞瘤、间胶质瘤等)。2.来自脑膜者:如脑膜瘤。3.来自颅内腺体者:如垂体腺瘤。4.永自颅神经鞘者:如听神经瘤、三叉神经节肿
According to the statistics of different materials in the literature, brain tumors account for about 1.8% of all tumors in the human body.

This shows that brain tumor is not a rare disease. Due to many intracranial tissue components, embryos from different sources, so the type of intracranial tumors are also many. Commonly referred to clinically the scope includes the following: 1. From nerve tissue: such as glioma (glioblastoma, astrocytoma, medulloblastoma, glioma, etc.). 2.
