Les parties solides contiennent du calcium, et les kystes sont remplis de liquide. La tumeur se trouve dans la partie centrale de l’encéphale, au-dessus de l’hypophyse. Elle se trouve aussi près d’autres parties importantes de l’encéphale comme l’hypothalamus, les voies du nerf optique et le troisième ventricule.

Les voies du nerf optique, qui jouent un rôle dans la vision, peuvent aussi être touchées. </p> <p>Il existe diverses approches de traitement, selon l’âge de l’enfant et les caractéristiques de la tumeur.

It is believed that it grows when a baby is developing, and cells that normally disappear during development don't disappear and form a craniopharyngioma. </p><p>There is no way to predict that a child will get a tumour. Nobody is to blame if a child develops a tumour.</p><p>Researchers have also been studying whether environmental factors, such as food or chemicals, can cause brain tumours. At the moment, there is no definite proof that there is a connection. </p><h2>How many other children have craniopharyngiomas?</h2><p>Craniopharyngiomas account for about 3 to 5 out of every 100 brain tumours in children. They are usually found in children aged five to 10. </p><h2>What are the medical symptoms of a craniopharyngioma?</h2><p>Common symptoms are headaches, vomiting, and problems with vision. The tumour presses on the hypothalamus and pituitary gland which both produce hormones, which are chemicals that send signals to other parts of the body. As a result, the tumour affects the release of hormones. Because hormone levels are changed, the child may experience poor growth, delayed puberty (or in rare cases, early puberty), and appetite changes. A child may also develop diabetes insipidus, which causes intense thirst and increased need to pee (urinate). </p><p>Other symptoms can include:</p><ul><li>fatigue </li><li>sleepiness in the daytime</li><li>waking at night</li><li>significant weight gain</li><li>behaviour changes</li><li>memory problems</li></ul><p>For more information please see:</p><ul><li> <a href="/Article?contentid=1330&language=English">Diagnosis of Craniopharyngiomas</a></li><li> <a href="/Article?contentid=1370&language=English">Treatment of Craniopharyngiomas </a></li></ul>CraniopharyngiomasFalse
