Brain Tumor Types

These tumors arise from the supportive cells in the brain, called glial cells. Gliomas are the most common type of brain tumor and can be further classified into different subtypes based on the type of glial cell they originate from.

These tumors arise from the astrocytes, which are star-shaped glial cells that provide support and nourishment to neurons. Astrocytomas can be either low-grade or high-grade and are the most common type of glioma.

These tumors arise from the oligodendrocytes, which are glial cells that produce myelin, the fatty substance that insulates nerve fibers. Oligodendrogliomas are less common than astrocytomas but are more likely to be low-grade.

These tumors arise from the ependymal cells, which line the ventricles and central canal of the spinal cord. Ependymomas are rare but can be either benign or malignant.

These tumors arise from the meninges, which are the membranes that cover the brain and spinal cord. Meningiomas are usually slow-growing and benign, but they can sometimes be malignant.

These tumors arise from the pituitary gland, which is a small gland at the base of the brain that produces hormones. Pituitary adenomas are usually benign and can be treated with medication or surgery.

These tumors arise from the Schwann cells, which are the cells that wrap around nerves to provide insulation. Schwannomas are usually benign and can be treated with surgery.

These tumors arise from the cerebellum, which is the part of the brain that controls movement and coordination. They are most commonly found in children and are highly malignant.

These tumors arise from embryonic tissue that is left over from early development. Craniopharyngiomas are usually benign but can cause problems by pressing on nearby structures in the brain.

These tumors arise from the pineal gland, which is a small gland in the brain that produces melatonin. Pineal gland tumors are rare but can cause problems by producing too much melatonin or by pressing on nearby structures in the brain.

These tumors arise from the germ cells, which are the cells that give rise to eggs or sperm. Germ cell tumors are rare but can occur in the brain, particularly in the pineal gland or the area around the pituitary gland.

These tumors arise from the blood vessels in the brain and spinal cord. They are rare but can be associated with a genetic condition called von Hippel-Lindau disease.

This is a highly aggressive and malignant type of astrocytoma, the most common type of brain tumor. Glioblastomas are typically fast-growing and can spread quickly throughout the brain. They are difficult to treat and have a poor prognosis, with an average survival time of less than two years.

Primary CNS Lymphoma (PCNSL) is a rare and aggressive form of extranodal non-Hodgkin lymphoma that originates in the central nervous system (CNS), including the brain, eyes (ocular lymphoma), and cerebrospinal fluid (CSF), without systemic involvement at diagnosis. Advances in treatment, particularly the introduction of high-dose methotrexate (HD-MTX)-based chemotherapy, have significantly improved patient outcomes over the past few decades. However, PCNSL remains a challenging disease due to its relapse potential and neurological complications, and research is actively ongoing to develop more effective and less toxic treatment strategies.
