Each gets its name from the type of cells involved. Examples include: 1  Gliomas.2  These tumors begin in the brain or spinal cord and include astrocytomas, ependymoma, glioblastomas, oligoastrocytomas and oligodendrogliomas. 3  Meningiomas.any different types of primary brain tumors exist.

1 Astrocytic tumors include astrocytomas (can be noncancerous), anaplastic astrocytomas, and glioblastomas. 2  Oligodendroglial tumors. Some primary brain tumors are made up of both astrocytic and oligodendrocytic tumors. These are called mixed gliomas.  Glioblastomas are the most aggressive type of primary brain tumor.
