Pituitary gland tumours or adenomas may cause hormonal and/ or visual disturbances.
What are the symptoms of pituitary tumours? Why are there vision defects in Pituitary tumours? What is its treatment? Can Pituitary tumours be cured? How is the operation for pituitary tumour done?
These are some of the FAQs regarding pituitary gland adenomas. In this video, Dr Jaydev Panchawagh explains with the help of an MRI how closely the tumour is in association with the optic nerves-nerves responsible for vision, and how if it grows to a very large size, it can cause compression on the nerves and cause headache and visual and field defects, most commonly bitemporal hemianopia. Occasionally, it can cause blindness.
Typically, the symptoms are caused by hormonal disturbances, either increased secretion or decreased secretion. The pituitary gland secretes some very important hormones like: Growth Hormone GH, Thyroid Stimulating Hormone TSH, Adrenocorticotropic hormone ACTH, Prolactin etc. An increased secretion can cause various symptoms like enlarged hands and feet, increased hair growth, coarse facial features, menstrual disturbances, nervousness and irritability, weight loss or weight gain, milky discharge from breasts, pimples, stretch marks, increased blood sugar, increased blood pressure etc, just to name a few.
The cause for a pituitary tumour is not known, but occasionally can run in families.
When the size of the tumour is more than 1 cm, they are called pituitary macroadenomas and when they are less than 1 cm, they are called pituitary microadenomas.
Not all pituitary tumours are hormone-secreting.
Treatment for pituitary tumours is generally surgery. This is mostly done through the nose using and endoscope or microscope. Complete removal is generally possible, and so prognosis for surgical resection of pituitary tumours is excellent. Patients may need to take some supplements after the operation.
Prolactinomas, Acromegaly, Microadenomas, Macroadenomas, functioning and non-functioning Pituitary tumours, pituitary apoplexy are some of the terms used to describe various types.
