Some pituitary tumors cause symptoms while others don’t have symptoms.
Pituitary tumors that make hormones (functioning) can have signs and symptoms depending on what kind of hormone they produce and the ones that do not make hormones (nonfunctioning) are related to the pressure they put on other structures and growth.
The smaller tumors are also known as microadenomas while large tumors are also known as macroadenomas that has a measure of about 1 centimeter and can put pressure on the normal pituitary gland because of its size.
The symptoms of pituitary tumor related to pressure are headache and vision of loss or particularly loss of peripheral vision.

Experts suspect that there is genetic alterations are involved on how these tumors developed.
4 Making a Diagnosis
Your doctor will first conduct a physical exam and several tests to make a diagnosis of pituitary tumors. Tests include:
blood and urine tests – to check if you have deficiency or overproduction of hormones;
vision testing – if the tumor has damaged your sight or peripheral vision;
brain imaging – MRI or CT scan of your brain to check the location and size of the tumor.
Your doctor may also refer you to an endocrinologist.
