| This adult tumor crosses the Corpus Collosum, stains for GFAP, and has tumor cells bordering areas of necrosis and hemorrhage on Light microscopy | Glioblastoma Multiforme (Grade IV Astrocytoma) |
| This adult tumor has concentric arranged calcifications, and arises from arachnoid cells external to the brain. | Meningioma |
| This adult tumor is S-100 Positive, and commonly occurs in the cerebellar pontine angle, bilaterally in neurofibromatosis 2 (chromosome 22) | Schwannoma |
| This adult tumor is often in the frontal lobes, and has round nuclei with clear cytoplasm that is often calcified. You may see a chicken wire capillary pattern | Oligodendroma |
| This Adult Tumor is often prolactin secreting, causes bitemporal hemianopsia, what is its origin? | Rathke's Pouch (its a pituitary adenoma) |
| This childhood tumor is well circumscribed and contains eosinophilic corkscrew fibers. | Pilocytic Astrocytoma. Low grade |
| This childhood tumor is most often in the cerebellum, and contains rosettes or pervivascular pseudorosettes, and can cause hydrocephalus. It is a form of a primintive neuroectoderm tumor | Medulloblastoma. |
| This tumor is often in the 4th ventricle, and has characteristic rod shaped basal ciliary bodies found near the nucleus, as well as pervascular pseudorosettes | Ependyoma |
