The topic Neuroepithelioma Gliomatosum you are seeking is a synonym, or alternative name, or is closely related to the medical condition Ependymoma.

Quick Summary:

  • An Ependymoma is a type of brain tumor that originates from a brain support cell, called an ependymal cell
  • Ependymal cells line the brain and spinal cord cavities (known as ventricles). These are of importance, because they produce and store the cerebrospinal fluid (CSF). The CSF protects the brain, reduces pressure, disposes waste, and transports hormones
  • Ependymoma type tumors make up for 6% of the total number of pediatric brain tumors. 90% of pediatric Ependymomas are found in the posterior fossa region of the brain

Ependymoma subtype is described, based upon its locational relationship to a membrane in the brain, called the tentorium. The two types of Ependymoma are called:

  • Supratentorial Ependymoma: This type is located above the tentorium, in the top 2/3rd of the brain
  • Infratentorial or posterior fossa Ependymoma: This type is located below the tentorium, in the bottom 1/3rd of the brain, or the brainstem

When a healthcare provider performs a brain imagining study, they are able to classify the tumor into one or the other subtype. Depending on the location of the tumor, the signs and symptoms, treatment, and prognosis, may vary.

Please find comprehensive information on Ependymoma regarding definition, distribution, risk factors, causes, signs & symptoms, diagnosis, complications, treatment, prevention, prognosis, and additional useful information HERE.
