Glioma: Definition, Causes, Symptoms

Glioma definition medical

Gliomas are the most common primary tumor of the brain, about 33% of (cases of) brain tumors. Gliomas originate from glial cells in the brain. Glial cells are tissue cells that surround and support nerve cells in the brain.

Three types of tumor cells that are usually found in the cases of glioma: astrocytes, oligodendrocyte, and ependymal cells. Glioma is called intrinsic brain tumors because they are in the brain tissue and often blends with healthy brain tissue.

Glioma Stage

How malignant glioma depends on the stage. There are stages 1 to 4 based on the type of tumor cells seen under a microscope. Stage I is the lowest malignancy, and class 4 is the most malignant. Low stage (1 or 2) has a characteristic of growing relatively slowly, while high stage (3 or 4) has more malignant characteristics, with rapid growth and spread to healthy brain tissue.

Types of glioma

Glioma also classified based on the type of cell. Types of glioma are:

1. Astrocytoma – develops in the cells of the connective tissue, called astrocytes
2. brainstem Glioma – develop in the brain stem
3. Ependymoma – evolved from ependymal cells
4. mixed Glioma – evolving from more than one type of glial cells
5. Oligodendroglioma – develops in the cells of the brain's support network, called oligodendrocytes
6. the optic nerve Glioma-grown in or around the optic nerve (visions).

Symptoms of glioma

Glioma cause symptoms by suppressing the brain or spinal cord. The most common symptoms are:
  • Headaches
  • Seizures
  • Change of personality
  • A weakness in an arm or leg
  • Numb
  • Nausea and vomiting
  • Loss of vision
Symptoms of glioma appear slowly and may initially be mild. Even some glioma does not cause any symptoms and may be new undiagnosed when patients see a doctor for symptoms of other conditions are checked.

Diagnosis Of Glioma

If you have symptoms of a brain tumor, your doctor will first ask about symptoms that appear. Next, the doctor will evaluate your complete medical history and perform a physical examination. In addition to checking out your overall health, your doctor will perform a neurological examination to observe the way you walk, talk, and move.

The doctor may examine your eyes to look for swelling caused by pressure on the optic nerve of you. The optic nerve connects the eye to the brain. This swelling called edema papil. This is a sign that requires immediate medical attention.

Glioma diagnosis procedures include:

  • Medical history Interview and physical examination: This includes questions about symptoms, personal and family health history of the patient. 
  • Neurological Examination: tests of vision, hearing, reflexes, coordination, balance, and the ability to think and remember.
  • Examination of brain scans: Magnetic Resonance Imaging (MRI) and computed tomography (CT or CAT scan), which uses a computer to make the image detail of the brain, is the most common scan used to diagnose brain tumors.
  • Biopsy: this is the procedure to take the fraction of tumor tissue for examination under a microscope.

Treatment for Glioma

The best treatment for each patient considering the location of the tumor, symptoms, risks, and benefits of the various treatment options that exist.

Treatment for glioma tailored to each patient that includes surgery, radiation therapy, chemotherapy, or observation. The team best does treatment for patients with brain tumors. This includes a neurologist, neuro-medical oncology, radiation therapy, and pathologist. Team SNEI, we hold a multi-disciplinary Conference on brain tumor each download with all medical specialties in attendance to review each case of the tumor and make the best decision to enforce a diagnosis and plan of care of patients.

Operation on glioma

The operation procedure is the most common early treatment for glioma. Biopsy of tissue taken during operation providing tissue samples to a pathologist, then the doctors can make an accurate diagnosis of the tumor, which is very important to get further treatment. The operation also aims to take tissue tumors and reduce pressure on the brain caused by the tumor.

Types of glioma surgery :
  • Craniotomy
  • Intraoperative brain mapping (awake brain surgery)
