Abnormally high levels of pituitary hormones found accidentally may be the first sign of a pituitary tumor. Your doctor may arrange for you to have a CT scan or MRI scan-to confirm whether a pituitary tumour is present. For your doctors to plan your treatment, they need to find out as much as possible about the type, position and size of the tumour, so you may have a number of tests and investigations. You may undergo eye tests to detect pressure on the optic nerve, which may indicate that a tumour is present. A simple test may also be done to check your visual fields(range of vision).
