Learn About Posterior Fossa Tumor

What is the definition of Posterior Fossa Tumor?

Posterior fossa tumor is a type of brain tumor located in or near the bottom of the skull.

What are the alternative names for Posterior Fossa Tumor?

Infratentorial brain tumors; Brainstem glioma; Cerebellar tumor

What are the causes of Posterior Fossa Tumor?

The posterior fossa is a small space in the skull, found near the brainstem and cerebellum. The cerebellum is the part of the brain responsible for balance and coordinated movements. The brainstem is responsible for controlling vital body functions, such as breathing.

If a tumor grows in the area of the posterior fossa, it can block the flow of spinal fluid and cause increased pressure on the brain and spinal cord.

Most tumors of the posterior fossa are primary brain cancers. They start in the brain, rather than spreading from somewhere else in the body.

Posterior fossa tumors have no known causes or risk factors.

What are the symptoms of Posterior Fossa Tumor?

Symptoms occur very early with posterior fossa tumors and may include:

  • Drowsiness
  • Headache
  • Imbalance
  • Nausea
  • Uncoordinated walk (ataxia)
  • Vomiting

Symptoms from posterior fossa tumors also occur when the tumor damages local structures, such as the cranial nerves. Symptoms of cranial nerve damage include:

  • Dilated pupils
  • Eye problems
  • Face muscle weakness
  • Hearing loss
  • Loss of feeling in part of the face
  • Taste problems
  • Unsteadiness when walking
  • Vision problems

What are the current treatments for Posterior Fossa Tumor?

Most tumors of the posterior fossa are removed with surgery, even if they are not cancerous. There is limited space in the posterior fossa, and the tumor can easily press on critical structures if it grows.

Depending on the type and size of the tumor, radiation treatment may also be used after surgery.

A Phase 1/2 Trial of Selinexor (KPT-330) and Radiation Therapy in Newly-Diagnosed Pediatric Diffuse Intrinsic Pontine Glioma (DIPG) and High-Grade Glioma (HGG)

Summary: This phase I/II trial tests the safety, side effects, and best dose of selinexor given in combination with standard radiation therapy in treating children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) with a genetic change called H3 K27M mutation. It also tests whether combination of selinexor and standard radiation therapy works to shrink...

A Phase I Study of Savolitinib in Recurrent, Progressive or Refractory Medulloblastoma, High-Grade Glioma, Diffuse Intrinsic Pontine Glioma, and CNS Tumors Harboring MET Aberrations

Summary: This phase I trial studies the side effects and best dose of volitinib in treating patients with primary central nervous system (CNS) tumors that have come back (recurrent) or does not respond to treatment (refractory). Volitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
