Final diagnosis
Tissue from sella, transsphenoidal removal :
- Presence of portion of cyst lined by non-keratinizing squamous epithelium, cholesterol crystal and amorphous cosinophilic material
- Few pieces of anterior pituitary tissue with crush artifact
Comment : differential diagnosis includes rathke eleft cyst or cystic craniopharyngioma. However, diagnostic tissue of craniopharyngioma is not present(e.g. wetkeratin); correlation with imaging study is suggested.
