Background Information About Childhood Craniopharyngioma
Incidence and Presentation
Craniopharyngiomas are relatively rare pediatric tumors, accounting for about 6% of all intracranial tumors in children.[1-3] They are believed to be congenital in origin, arising from ectodermal remnants, Rathke cleft, or other embryonal epithelium in the sellar and/or parasellar area. No predisposing factors have been identified.
Because craniopharyngiomas occur in the region of the pituitary gland, endocrine function and growth may be affected. Additionally, the close proximity of the tumor to the optic nerves and chiasm may result in vision problems. Some patients present with obstructive hydrocephalus due to tumor obstruction of the third ventricle. Extremely rarely, the tumor may predominate in the posterior fossa with presenting symptoms of headache, diplopia, ataxia, and hearing loss.
