Pituitary Adenoma

The pituitary gland lies in the sella turcica (a saddle shaped cavity at the base of the skull) and is attached to the brain by the pituitary stalk. Tumours may produce hormones in excessive amount or cause damage by pressing on the nerves on their way to the eye.

Gamma Knife Radiosurgery is effective in halting the growth of the tumour and if the optic nerve/chiasm is not too close, then sufficient dose can be given to stop the abnormal hormone production. Large tumours have to be reduced by operation or medication first.
