Questions on this page
What is a pituitary tumour?
A pituitary tumour is an abnormal growth arising in the pituitary gland. Most pituitary tumours are benign.
Are all pituitary tumours hormone-producing?
No. Some produce excess hormones, while others do not produce hormones and are called non-functioning pituitary tumours.
What symptoms can a pituitary tumour cause?
Symptoms depend on the tumour and the hormones involved. They can include headache, visual problems, menstrual changes, infertility, sexual dysfunction, abnormal growth, weight changes or symptoms of hormone deficiency.
What is a pituitary incidentaloma?
A pituitary incidentaloma is a pituitary lesion discovered unexpectedly during brain imaging performed for another reason.
Does every pituitary tumour require treatment?
No. Some small, non-functioning tumours can be monitored with hormonal assessment, visual evaluation and repeat MRI when appropriate.
When is pituitary surgery required?
Surgery may be considered for selected tumours, particularly when there is significant pressure on the optic pathways, certain hormone-producing tumours, or other specific indications.
Can pituitary tumours come back?
Some pituitary tumours can recur or regrow after treatment, so long-term follow-up may be necessary.
