Craniopharyngioma
Craniopharyngioma is a benign tumour that is locally destructive. It arises from remnants of Rathke's pouch (embryological pouch that migrates from the foregut into the base of skull to form the anterior pituitary). It is most common in children but also occurs later in life; it accounts for about 2% of brain malignancies. Surgery and radiotherapy both have a role in the treatment of this condition.
