Pediatric ependymoma
Pediatric Ependymoma
Pediatric ependymoma (/pɛdiːætrɪk ɛpɛndɪmoʊmə/) is a rare type of brain tumor that originates in the ependymal cells lining the ventricles of the brain and the central canal of the spinal cord.
Etymology
The term "ependymoma" is derived from the Greek words "ependyma" meaning "upper garment" and "-oma" meaning "tumor". The term "pediatric" is derived from the Greek words "pais" meaning "child" and "-iatric" meaning "medical treatment".
Definition
Pediatric ependymomas are a subtype of ependymoma that occur in children. They are typically located in the posterior fossa, particularly the fourth ventricle, but can also occur in the spinal cord. These tumors can cause a variety of symptoms, including hydrocephalus, headache, nausea, vomiting, and problems with balance and coordination.

- Hydrocephalus: A condition in which there is an accumulation of cerebrospinal fluid within the brain, causing increased pressure.
- Posterior fossa: The small space in the skull, found near the brainstem and cerebellum.
Treatment
Treatment for pediatric ependymoma typically involves surgery to remove as much of the tumor as possible, followed by radiation therapy. In some cases, chemotherapy may also be used. The specific treatment plan will depend on a variety of factors, including the child's age, the location and size of the tumor, and the child's overall health.
Prognosis
The prognosis for children with ependymoma varies widely and depends on many factors, including the child's age, the location and size of the tumor, and the extent of tumor removal. With appropriate treatment, many children with ependymoma can achieve long-term survival.
