Pituitary tumours 

The pituitary gland is located at the base of the brain, behind the eyes. It produces chemical messengers called hormones. These are produced by the pituitary gland and released into the blood stream. They, in turn, control other glands in the body, including the adrenal glands and thyroid gland, which then control important body functions.

Most pituitary tumours are pituitary adenomas, which are benign, slow-growing tumours that arise from cells in the pituitary gland. Symptoms of the pituitary tumour are generally caused by the tumour producing too much of a certain hormone, by preventing the normal gland from producing enough hormones or by causing pressure on the nerves to the eyes. Increasingly pituitary tumours are found on routine scans for often completely unrelated problems such as headaches.

You will need different tests to assess the size and effects of the tumour, such as eye tests, a CT scan or an MRI scan as well as an assessment of the hormones that the pituitary gland produces. Often, a specialist endocrinologist will see you and assess your hormones before any particular treatment is recommended.

If the pituitary tumour needs treatment, surgery tends to be the first line treatment in most cases. Your neurosurgeon will talk to you about the best treatment option for you, taking into consideration the scan and blood test results.

Most pituitary surgery is undertaken through the nose so you will not have a visible wound after surgery. This is called a transsphenoidal hypophysectomy as it is undertaken via the sphenoid sinus which is an air sinus that sits at the back of your nose. It is done under general anaesthetic. If the tumour is very large, your neurosurgeon might decide that the best option for you is a craniotomy (surgery through your head).

We sometimes suggest treating the pituitary tumour with medication. This is particularly if the pituitary tumour produces too much of a hormone called Prolactin. Some people will need radiotherapy after surgery or instead of surgery. Some people with very small tumours may have a specialised type of targeted radiotherapy called stereotactic radiosurgery.

You might need to take medication if your hormones have been affected either by the tumour or as a result of surgery. This is called hormone replacement.
