Optic glioma

Glioma - optic; Optic nerve glioma; Juvenile pilocytic astrocytoma; Brain cancer - optic glioma

Gliomas are tumors that grow in various parts of the brain. Optic gliomas can affect:

  • One or both of the optic nerves that carry visual information to the brain from each eye
  • The optic chiasm, the area where the optic nerves cross each other in front of the hypothalamus of the brain

An optic glioma may also grow along with a hypothalamic glioma.

Neurofibromatosis I, enlarged optic foramen

This x-ray shows the skull of a child with neurofibromatosis (NF-1). This child developed visual difficulties and was discovered to have a glioma (nerve tumor) in the optic nerve. The tumor has enlarged the bony opening (optic foramen), through which the optic nerve passes. This can be seen on the right side of picture.
