Craniopharyngiomas are generally benign, but are known to recur after resection. Recent research has demonstrated a malignant (but rare) tendency of craniopharyngiomas. These malignant craniopharyngiomas are very rare, but are associated with poor prognosis.
is Craniopharyngioma malignant?
In contrast, “malignant” tumors have cells that can invade and spread if not treated. Craniopharyngioma is a benign brain tumor that accounts for about 3-9% of all pediatric CNS tumors. This tumor results from abnormal overgrowth of a part of the brain called Rathke’s pouch, located near the pituitary gland.
can you die from Craniopharyngioma?
In most of the reports of outcomes, the mortality is reported up to about 10 years, but there is a significant mortality of patients with craniopharyngioma even more than 10 years after diagnosis of the disease. After 10 years there were 4 deaths among these 17 patients, and none of them were from tumor growth.
what type of tumor is a Craniopharyngioma?
Craniopharyngioma is a rare type of brain tumor that mostly affects children between the ages of 5 and 14. Adults sometimes get them, too. They grow near the pituitary gland at the base of the brain. Craniopharyngiomas are made up of solid parts and fluid-filled pockets called cysts.
Is Craniopharyngioma genetic?

Craniopharyngiomas are rare, benign brain tumours with potentially devastating clinical effects, including visual defects, severe headaches, impaired intellectual function and obesity. The BRAF mutation is the first reported genetic alteration associated with the papillary subtype
How fast does Craniopharyngioma grow?

What is Rathke’s pouch?
In embryogenesis, Rathke’s pouch is an evagination at the roof of the developing mouth in front of the buccopharyngeal membrane. It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system.
What is the difference between pituitary adenoma and craniopharyngioma?
However, pituitary adenomas and craniopharyngiomas differ from each other, as follows: 1) pituitary adenomas are the third most common type of intracranial tumor and represent a significant proportion of brain tumors affecting humans and approximately 80% of sellar lesions, whereas craniopharyngiomas represent only 1
