Question: What causes Craniopharyngioma ?
Answer: What causes craniopharyngioma? Craniopharyngiomas are thought to arise from epithelial remnants of the craniopharyngeal duct or Rathke's pouch (adamantinomatous type tumours) or from metaplasia of squamous epithelial cell rests that are remnants of the part of the stomadeum that contributed to the buccal mucosa (squamous papillary type tumours).

Question: What are the treatments for Craniopharyngioma ?
Answer: How might craniopharyngiomas be treated? Traditionally, surgery has been the main treatment for craniopharyngioma. However, radiation treatment instead of surgery may be the best choice for some patients. In tumors that cannot be removed completely with surgery alone, radiation therapy is usually necessary. If the tumor has a classic appearance on CT scan, then even a biopsy may not be necessary, if treatment with radiation alone is planned. This tumor is best treated at a center with experience managing craniopharyngiomas.
