 A

Derived from Rathke’s pouch

 B

Contains epithelial cells

 C

Present in sella or infra-sellar location

 D

Causes visual disturbances

Ans. C

Explanation:

Answer is C (Present in sella or infrasellar location):

Some of these lesions arise from the sella, but most are suprasellar Q (Not infra-sellar). They arise from near the pituitary stalk and commonly extend into the supra sellar cistern.

  • Craniopharyngiomas arise from Rathke’s pouch and constitute 3-5% of all intracranial neoplasms.
  • Some of these lesions arise from the sella, but most are suprasellar Q (Not infra-sellar). They arise from near the pituitary stalk and commonly extend into the supra sellar cistern.
  • Consists of nests of cords of stratified squamous or columnar epithelium embedded in a spongy reticulum — Robbins 61h/1129
  • Visual complaints are the presenting feature in about 80% of adults and 60% of children.
