Glioma (Astrocytoma, Oligodendroglioma & Ependymoma)

Glioma (Astrocytoma, Oligodendroglioma & Ependymoma)

The term glioma is used to describe any tumor that arises from the brain’s supportive tissue. This tissue, called “glia,” helps to keep the neurons functioning well and in place.

The three types of tumors that originate in glial cells are:

  • Astrocytomas – arise from astrocytes, the star-shaped cells that make up the brain’s glue-like supportive tissue.
  • Oligodendrogliomas – come from oligodendrocytes, one of the types of cells that make up the supportive, or glial, tissue of the brain. They can be low-grade (grade II) or high-grade (grade III, or anaplastic).
  • Ependymomas – arise from the ependymal cells that line the ventricles of the brain and the center of the spinal cord. Ependymomas are divided into four major types:
    • Subependymomas (grade I): Typically slow-growing tumors.
    • Myxopapillary ependymomas (grade I): Typically slow-growing tumors.
    • Ependymomas (grade II): The most common of the ependymal tumors. This type can be further divided into the following subtypes: cellular ependymomas, papillary ependymomas, clear cell ependymomas, and tancytic ependymomas.
    • Anaplastic ependymomas (grade III): Typically faster-growing tumors.

Glioma Symptoms

Glioma symptoms are similar to those of other malignant brain tumors and depend on the particular area of the brain that is affected. Glioma symptoms include:

  • Cognitive decline
  • Headache – affect about half of all people with a brain tumor
  • Language problems
  • Loss of muscle control
  • Memory loss
  • Personality changes
  • Physical weakness
  • Seizures
  • Visual symptoms

Getting Diagnosed

Our team of specialists provides the most up-to-date evaluations using the latest diagnostic and imaging technology.

We work very closely with the departments of Neurosurgery, Interventional Neuroradiology, Neurology and Radiation Oncology, as well as the Normal Pressure Hydrocephalus Center and Skull Base Center to ensure an accurate diagnosis and the appropriate treatment for the best outcome.
