The ventricles are areas in the brain&nbsp;that are paths for cerebrospinal fluid. This protective fluid cushions the brain and spine. </span></p> <p><span style="font-size: 1em; line-height: 1.4em;">Most ependymomas develop in children under age 5.</span></p> <h3>More to Know</h3> <p>The ependyma is a thin layer of cells that lines parts of the brain and spinal cord. These cells make cerebrospinal fluid. When an ependymal cell has a defect and grows out of control, it forms a tumor called an ependymoma.</p> <p><span style="line-height: 16.8px;">Most&nbsp;</span><span style="line-height: 16.8px;">ependymomas&nbsp;</span><span style="line-height: 16.8px; font-size: 1em;">do not spread (metastasize) to other areas of the body.&nbsp;</span></p> <p>Doctors define ependymomas according to their location. Tumors in the top part of the head are called <strong>supratentorial</strong>. Tumors in the back of the head are called <strong>infratentorial</strong>. They are more common than supratentorial tumors.&nbsp;</p> <p>Kids with&nbsp;<span style="line-height: 16.8px;">ependymomas</span><span style="line-height: 16.8px;">&nbsp;will feel sick, throw up,&nbsp;</span>and get headaches from increased pressure in the brain. They might feel weak and have vision problems. Infratentorial tumors can also cause trouble with coordination.&nbsp;In infants, a fast increase in head measurement can be a sign of a tumor.&nbsp;</p> <p><span style="font-size: 1em; line-height: 1.4em;">If an ependymoma is in the spinal cord, it can cause pain and changes in sensation. A child might also feel weak in some parts of the body, depending on where the tumor is located.</span></p> <p>Doctors often can do surgery on ependymomas in the top of the head and spinal cord. Some of these tumors may also need&nbsp;<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/radiation.html/">radiation</a>. Ependymomas in the back of the head usually require much more aggressive treatment with surgery, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/chemotherapy.html/">chemotherapy</a>, and radiation.</p> <h3>Keep in Mind</h3> <p>If the tumor can be completely removed, patients with ependymomas may need no additional treatments. However, some ependymomas will require further treatment &mdash; usually radiation therapy and sometimes also chemotherapy.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
