The tumor rarely occurs in adults. A pilocytic astrocytoma is a brain tumor that originates from star-shaped cells called astrocytes. The tumor may be in the form of a cyst and usually does not spread to nearby tissues.

Symptoms vary depending upon the size and location of the tumor. Gliomas are tumors that form from glial cells. They usually arise in the cerebellum near the brainstem in the hypothalamic region or the optic chiasm but they may occur in any area where astrocytes are present including the cerebral hemispheres and the spinal cord.

An astrocyte is a type of glial cellGlial cells hold nerve cells in place bring food and oxygen to them and help protect them from disease such as infection. Gliomas can be put into groups according to how quickly they are likely to grow. The following are treatments for pilocytic astrocytomas.
