What is a pituitary adenoma?
A pituitary adenoma is a benign (not cancer) tumor found in your pituitary. The pituitary is a small gland in your brain that makes hormones to control other organs and tissues in your body. A pituitary adenoma can put pressure on nearby nerves and brain tissue. A pituitary adenoma can also release high levels of hormones that affect how other organs and tissues work.
What are the signs and symptoms of a pituitary adenoma?
Your signs and symptoms will depend on the size of the tumor and the hormones released. The following are the most common signs and symptoms of a pituitary adenoma:
- Changes in your vision
- Tender or enlarged breasts
- Difficulty getting pregnant
How is a pituitary adenoma diagnosed?
- Blood tests are done to measure hormone levels and get information about your overall health.
- A 24 hour urine test is done to check the amount of hormone in your urine. You will need to collect all your urine for 1 day. Healthcare providers will give you a container to hold your urine and keep it cold.
- A CT or MRI will show the size and location of the pituitary adenoma. You may be given contrast dye to help the tumor show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast dye. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
How is a pituitary adenoma treated?
