Quick Answer: What is a common type of brain tumor of the brainstem?

Brainstem glioma generally refers to all gliomas that are located in the brainstem. Typically these tumors are astrocytomas, and can be grades I-IV.

What kind of tumor is on brain stem?

About brain stem glioma

Brain stem glioma is a type of central nervous system (CNS; brain and spinal cord) tumor. This type of tumor begins when healthy cells in the brain stem change and grow out of control, forming a mass called a tumor. A tumor can be cancerous or benign.

What is the most common type of brain tumor?

In fact, meningioma is the most common brain tumor, accounting for about 30 percent of them. Meningioma tumors are often benign: You may not even need surgery.

How common are brain stem tumors in adults?

Brainstem gliomas are not nearly as common in adults as they are in children. They are likely the final common consequence not of a single disease process but of several. They can be difficult to diagnose, and are challenging to treat. Clinical studies of this diagnosis are few and generally small.

What is the most common brain tumor in adults?


  • Anaplastic (grade III) astrocytomas.
  • Glioblastomas (grade IV), which are the fastest growing. These tumors make up more than half of all gliomas and are the most common malignant brain tumors in adults.

How serious is a tumor on the brain stem?

The brainstem, where the brain connects to the spinal cord, controls such basic functions as breathing, heartbeat, and other critical functions. Tumors that develop in this area of the brain are especially difficult to treat, since any intervention in the area can cause devastating neurological damage.

Are tumors on the brain stem operable?

Because the brain stem is a small area that is so essential for life, it might not be possible to surgically remove tumors in this area.

Where are brain tumors most common?

Their most common locations are the base of the skull and the lower portion of the spine. Although these tumors are benign, they may invade the adjacent bone and put pressure on nearby neural tissue. These are rare tumors, contributing to only 0.2 percent of all primary brain tumors.

Are most brain tumors benign?

About 700,000 Americans are living with a brain tumor, and 80% of primary brain tumors — tumors that began in the brain and did not spread from somewhere else in the body — are benign.

What causes brain stem tumors?

For most patients, the cause of brainstem glioma is unknown. However, there are a few rare, genetic conditions that may increase a patient’s chance of developing brainstem glioma. For example, patients with neurofibromatosis type 1 (NF1) may be more likely to develop brainstem gliomas, among other tumors.

What are the symptoms of a brain stem tumor?

Symptoms of brain tumors in the brainstem (base of brain) may include:

  • seizures.
  • endocrine problems (diabetes and/or hormone regulation)
  • visual changes or double vision.
  • headaches.
  • paralysis of nerves/muscles of the face, or half of the body.
  • respiratory changes.
  • increased intracranial pressure (ICP)

Can a tumor be removed from the brainstem?

Surgery is used to treat brain stem glioma only when the tumor looks focal on an MRI scan (see Diagnosis). This means that it may be possible to remove the tumor without damaging the brain, such as when a tumor grows out from the brain stem instead of into the brain stem.

What is a CNS tumor?

An adult central nervous system tumor is a disease in which abnormal cells form in the tissues of the brain and/or spinal cord. There are many types of brain and spinal cord tumors. The tumors are formed by the abnormal growth of cells and may begin in different parts of the brain or spinal cord.

What is the rarest type of brain tumor?

Ganglioglioma. A ganglioglioma is a rare type of brain tumor, accounting for approximately 1% of all brain tumors. Gangliogliomas occur when a single cell in the brain starts to divide into more cells, forming a tumor.

What is an oligodendroglioma?

Oligodendroglioma is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord. To get an accurate diagnosis, a piece of tumor tissue will be removed during surgery, if possible.
