^aUnique astrocytoma variants correspond to subependymoma (n = 3) and subependymal giant cell astrocytoma (n = 3).

^bMixed gliomas correspond to anaplastic oligoastrocytoma (n = 23) and oligoastrocytoma (n = 30).

^cGerm cell tumors and cysts correspond to germinoma (n = 4), mature teratoma (n = 1), dermoïd cyst (n = 3), and choriocarcinoma (n = 1).
