As the fetus develops, Rathke's pouch becomes one part of the pituitary gland, a small organ located near the bottom of the brain.</p> <p>In rare cases, remnants of Rathke's pouch develop into benign tumors. The tumors, called craniopharyngiomas, don't cause cancer but can cause problems in the brain and pituitary gland.</p> <p>Craniopharyngiomas can grow and press on the brain, pituitary gland, optic nerve (the nerve the connects the eye to the brain), or fluid-filled spaces within the brain. This can interfere with the production of hormones, affect the normal working of the brain, and cause headaches, slow growth, delayed puberty, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/vision.html/">vision</a> problems. Craniopharyngiomas are most common in children ages 5-14, but they can affect people of any age.</p> <p>Surgery to totally remove a craniopharyngioma can sometimes damage surrounding parts of the brain and cause a permanent shortage of some hormones. Therefore, for most patients, a neurosurgeon first removes part of the craniopharyngioma, and then uses <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/radiation.html/">radiation therapy</a> for any remaining tumor. This approach usually results in effective treatment of the tumor and better quality of life for the patient.</p> <h3>Keep in Mind</h3> <p>The overall survival rate for people with craniopharyngiomas is very high with treatment. If the tumor can be removed or treated with high doses of radiation, the chance of a permanent cure is about 80%-90%.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
BiopsiesDoctors order biopsies to examine tissue or cells when they're concerned about a problem such as an infection, inflammation, or cancer.https://kidshealth.org/ws/RadyChildrens/en/parents/biopsy.html/ff50e1b0-1450-45b5-b3d3-cf6db852408b

CAT Scan: HeadA head CAT scan is a painless test that uses a special X-ray machine to take pictures of a patient's brain, skull, and sinuses, as well as blood vessels in the head. It might be done to check for any number of conditions.https://kidshealth.org/ws/RadyChildrens/en/parents/ct-head.html/60a95789-3c39-4223-870e-3ebf4a3efdb4
Magnetic Resonance Imaging (MRI)Magnetic resonance imaging (MRI) is a safe and painless test that uses a magnetic field and radio waves to produce detailed pictures of the body's organs and structures.https://kidshealth.org/ws/RadyChildrens/en/parents/mri.html/90abcf12-963c-4847-be8d-979b06ecdbca
