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

/cra·nio·pha·ryn·gi·o·ma/ (kra″ne-o-fah-rin″je-o´mah) a tumor arising from cell rests derived from the infundibulum of the hypophysis or Rathke's pouch.

craniopharyngioma

[krā′nē·ōfərin′jē·ō′mə] pl. craniopharyngiomas, craniopharyngiomata
a congenital pituitary tumor, appearing most often in children and adolescents, that arises in cells derived from Rathke's pouch or the hypophyseal stalk. The lesion, a solid or cystic body ranging in size from 1 to 8 cm, may expand into the third ventricle or the temporal lobe and frequently becomes calcified. The tumor may interfere with pituitary function, damage the optic chiasm, disrupt hypothalamic control of the autonomic nervous system, and cause hydrocephalus. Increased intracranial pressure, severe headaches, vomiting, stunted growth, defective vision, irritability, somnolence, and infantile genitalia are often associated with the lesion in children. Development of the tumor after puberty usually results in amenorrhea in women and loss of libido and potency in men. Also called ameloblastoma, craniopharyngeal duct tumor, pituitary adamantinoma, Rathke's pouch tumor.

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.

craniopharyngioma (krā´nē-ōfərin´jēō´mə),

craniopharyngioma

a benign tumor arising from the cell rests derived from the infundibulum of the hypophysis or Rathke's pouch. Usually seen in young animals, they grow slowly. Their effects may be seen as a hypopituitarism, cranial nerve deficits or central nervous system dysfunction.
