The pituitary gland is located at the base of the brain and secretes hormones to regulate growth and control most of the other hormone based systems in the body. As the pituitary consists of glandular tissue, any tumour arising from it is termed an ‘Adenoma’. Although all pituitary adenomas are benign, due to the pituitary’s important role in hormone regulation and the proximity of the optical apparatus to the base of the skull, pituitary tumours can cause growth disturbances, changes in hormonal balance and visual disturbances.
In cases where the pituitary tumour is of significant size or is in direct contact with the optic nerves, surgery may be the initial treatment method to ‘debulk’ the tumour before treating the remain tumour with Gamma Knife.
