Types of Brain Tumors

Astrocytoma / Glioma

Astrocytomas are tumors that arise from brain cells called astrocytes. Gliomas originate from glial cells, most often astrocytes.

Atypical Teratoid / Rhabdoid Tumor (ATRT)

This rare, high-grade tumor occurs most commonly in children younger than 2.

Brain Stem Glioma

The brain stem consists of the midbrain, pons and medulla located deep in the posterior part of the brain.

Choroid Plexus Tumor

The choroid plexus papilloma is a rare, benign tumor most common in children under the age of 2.

Craniopharyngioma

Craniopharyngiomas result from the growth of cells that have failed to migrate to their usual area just below the back of the skull early in fetal development.

Ependymoma

An ependymoma is a rare type of primary brain or spinal cord tumor. Ependymomas are found throughout the central nervous system in the supratentorial (top of the head), posterior fossa (back of the head) and spinal compartments.

Ganglioglioma

These rare, benign tumors arise from ganglia-type cells, which are groups of nerve cells.

Germ Cell Tumors (Brain)

Different types of germ cells give rise to different types of tumors, including germinoma, embryonal carcinoma, endodermal sinus tumor and teratoma.

Gliomatosis Cerebri

This condition is similar to glioblastoma multiforme (GBM), but the cells of gliomatosis cerebri are more scattered and widespread.

Infant Brain Tumors

Medulloblastoma and ependymal tumors account for about 50 percent of tumors. Atypical teratoid / rhabdoid and choroid plexus tumors are most commonly found in children younger than 2.

Medulloblastoma

Medulloblastoma is a cancerous tumor—also called cerebellar primitive neuroectodermal tumor (PNET)—that starts in the region of the brain at the base of the skull, called the posterior fossa.

Oligodendroglioma

Oligodendrogliomas arise from oligodendrocytes, a type of supportive brain tissue.
