Table 3. Childhood Astrocytomas and Other Tumors of Glial Origin and Preferential Central Nervous System (CNS) Location
| Tumor Type | Preferential CNS location |
| Pilocytic astrocytoma | Optic nerve, optic chiasm/hypothalamus, thalamus and basal ganglia, cerebral hemispheres, cerebellum, brain stem, and spinal cord (rare) |
| Pleomorphic xanthoastrocytoma | Superficial location in cerebrum (temporal lobe preferentially) |
| Diffuse astrocytoma (including fibrillary) | Cerebrum (frontal and temporal lobes), brain stem, spinal cord, optic nerve, optic chiasm, optic pathway, hypothalamus, and thalamus |
| Anaplastic astrocytoma, glioblastoma | Cerebrum; occasionally cerebellum, brain stem, and spinal cord |
| Oligodendrogliomas | Cerebrum (frontal lobe preferentially followed by temporal, parietal, and occipital lobes), cerebellum, brain stem, and spinal cord |
| Oligoastrocytoma | Cerebral hemispheres (frontal lobe preferentially followed by the temporal lobe) |
| Gliomatosis cerebri | Cerebrum with or without brain stem involvement, cerebellum, and spinal cord |
