Brain Tumor in Children

Overview

"VSports app下载" What is a pediatric brain tumor?

There are many types of pediatric brain tumors, and they can occur at any age — from birth to adolescence and sometimes even in adulthood. Brain tumors (neoplasms) may be malignant (cancerous) or non-malignant (or benign, not cancerous) V体育安卓版.

How common are brain tumors in children?

Pediatric brain tumors are the most common type of cancer in children, affecting over 5,000 kids each year.

What are the different types of brain tumors in children? (VSports在线直播)

There are many types of pediatric brain tumors. They’re grouped by the kind of brain cell in which they develop. The main categories include: VSports最新版本.

• Gliomas.
• Embryonal tumors.
• Pineal tumors.
• Craniopharyngiomas.
• Germ cell tumors.
• Choroid plexus tumors.
• Schwannomas.
• Meningiomas.

Gliomas

Gliomas originate from glial cells in your brain. Glial cells support, nourish and protect your brain tissue and nerve cells or neurons. About half of all pediatric brain tumors are gliomas. Gliomas can be low-grade (slow growing) or high-grade (aggressive and fast growing) V体育平台登录.

Specific types include:

• Astrocytoma starts in a kind of glial cell called astrocytes. This type of tumor can form in your brain or spinal cord. It can be slow growing or aggressive.
• Oligodendroglioma starts in a type of glial cell called oligodendrocytes. This type of neoplasm is often found in the outer layer of your brain.
• Neuroglial cells consist of both glial cells and neuronal cells. Neuroglial tumors can occur in both your brain and spine and can often cause seizures.
• Ependymoma tumors begin in the ependymal cells, which line the fluid-filled spaces of your brain.

Embryonal tumors

Embryonal tumors start in fetal or embryonic cells in your central nervous system. These are cancerous tumors that can occur at any age, but they’re most common in babies and young children VSports注册入口.

Specific types of embryonal tumors include:

• Medulloblastoma,the most common type of embryonal tumor, starts in the back part of your brain — your cerebellum.
• Medulloepithelioma is a rare, fast-growing tumor that usually occurs in infants and young children.
• Atypical teratoid/rhabdoid tumor (ATRT) is a rare neoplasm that often starts in the cerebellum of very young children.
• Embryonal tumor with multilayered rosettes (ETMR) is an aggressive childhood brain cancer in your central nervous system.

Pineal tumors

A pineal tumor develops in your pineal gland V体育官网入口. Your pineal gland is in the middle of your brain and secretes a hormone called melatonin. There are different kinds of tumors that originate in your pineal gland. The tumors can be benign (non-cancerous) or malignant (cancerous).

Specific types of tumors that occur in the pineal gland in children include:

• Pineoblastoma, the most aggressive kind of embryonal tumor that can spread quickly to your brain and spine.
• Pineal parenchymal tumors, are of intermediate grade and mostly confined to the pineal region if detected on time.
• Germ cell tumors, which form from the embryonic tissue left in your pineal gland.

Craniopharyngiomas

Craniopharyngiomas are noncancerous tumors that start, near your pituitary gland. They arise from the embryonic tissue of your pituitary gland. Craniopharyngiomas are solid, cystic (sac of fluid) or mixed. They can be slow growing or fast growing V体育2025版.

These tumors can press on your pituitary gland, which makes hormones that regulate growth, blood pressure and reproduction. They also press on your hypothalamus, an important area of your brain that controls many functions, including body temperature, bodily fluids, emotions and much more. Craniopharyngiomas can also put pressure on your optic nerves, which can affect vision.

Germ cell tumors

Germ cell tumors are cancerous tumors that begin from embryonic cells called “germ” cells. During development, germ cells migrate outside of your brain to form ovaries or testes. The germ cells that remain in your brain can become cancerous to form germ cell tumors. These tumors can spread into your spine and cerebrospinal fluid (CSF).

Choroid plexus tumors

Choroid plexus tumors start in your choroid plexus, which lines the ventricles (fluid-filled cavities) of your brain. These tumors can be noncancerous (like choroid plexus papilloma) or cancerous (like choroid plexus carcinoma). Atypical choroid plexus papillomas are intermediate-grade tumors that can become malignant if not removed.

Schwannomas

Schwannomas are tumors that start in the Schwann cells, which insulate nerves in your brain. This type of tumor usually grows near the nerve that manages hearing and balance. It may also form near your spinal cord, causing weakness and problems with your senses. Although schwannomas are usually benign (not cancerous), they can be malignant (cancerous).

Meningiomas

Meningiomas are another type of brain tumor, but they’re less common in children. Meningiomas begin in your meninges, a layer of tissue around your brain. They can press on your brain and spinal cord. The majority of meningiomas are benign, but they can grow large enough to be life-threatening.
