craniopharyngioma

 [kra″ne-o-fah-rin″je-o´mah]
a tumor arising from cell rests derived from Rathke's pouch or some other part of the pituitary gland, often destroying the gland and causing deficits of the pituitary hormones.

cra·ni·o·pha·ryn·gi·o·ma

(krā'nē-ō-fă-rin'jē-ō'mă),
A suprasellar neoplasm that may be cystic; develops from the nests of epithelium derived from Rathke pouch; the histologic pattern, similar to that observed in adamantinomas, consists of nesting of squamous epithelium bordered by radially arranged cells; frequently accompanied by calcium deposition; may occassionally have a papillary architecture microscopically.

craniopharyngioma

A brain tumour affecting mainly children and arising from persistent primitive cells in the region of the pituitary gland. It causes headaches, visual field loss and delayed physical and mental development. Treatment is by surgical removal.

Craniopharyngioma

A tumor near the pituitary gland in the craniopharyngeal canal that often results in intracranial pressure.
