What size pituitary tumor should be removed?

Most patients have a macroadenoma (tumor > 1 cm) at the time of diagnosis. In this situation, surgery to remove as much of the tumor as possible is usually the first treatment.

What size pituitary tumor is considered large?

Large pituitary tumors — those measuring about 1 centimeter (slightly less than a half-inch) or larger — are known as macroadenomas. Smaller tumors are called microadenomas. Because of the size of macroadenomas, they can put pressure on the normal pituitary gland and nearby structures.

What drugs are used to shrink pituitary tumors?

Medicines used to treat pituitary tumors include: Bromocriptine and cabergoline for pituitary adenomas called prolactinomas, which produce too much of the hormone prolactin. These medications can treat prolactinomas by decreasing prolactin secretion and often shrink the tumor.

Is a pituitary tumor serious?

Most of these tumors are not cancerous. Pituitary cancer is very rare. Still, the tumors can cause serious problems, either because of their size (large tumors) or because they make extra hormones your body doesn’t need (functioning tumors). They’re typically treated with surgery, medicine, or radiation.

What is the most common type of pituitary tumor?

Below are the main types of pituitary tumors.

  • Nonfunctional adenomas (null cell adenomas) These tumors are the most common type.
  • Prolactin-producing tumors (prolactinomas) These benign tumors are also common.
  • ACTH-producing tumors.
  • Growth hormone-producing tumors.

How long does it take to cure pituitary tumor?

It can take up to 6 weeks to fully recover. The cuts the doctor made (incisions) may be sore for about 5 days after surgery. You may also have numbness and shooting pains near your wound, or swelling and bruising around your eyes.

How can you tell if a pituitary tumor is benign or malignant?

MRI or CT scans can detect tumors in the pituitary gland. And blood and urine tests can determine hormone levels. Even under a microscope, it’s difficult to recognize the difference between a cancerous and a noncancerous pituitary tumor.

Can pituitary tumors cause anger?

It has been documented that clinical depression and anxiety are common with pituitary disorders. Some patients report memory and mental confusion, anger and/or rage and even changes in a patient’s overall sense and awareness of themselves.

What do you call a tumor in the pituitary gland?

That area is called the adenohypophysis, or the anterior pituitary. Pituitary tumors rarely develop in the rear one-third of the pituitary gland, called the neurohypophysis or the posterior pituitary. The tumors are almost always benign and most are very successfully treatable.

How can you tell if your pituitary tumor has recurred?

If the tumor was producing a hormone that caused particular symptoms (Cushing’s, Acromegaly, prolactin tumor), the patient is usually the first to recognize this. Measurement of the appropriate hormone level in blood or urine is the most accurate method of determining if the tumor has recurred.

Can a tumor on the pituitary gland cause vision loss?

This depends on the type of tumor and the size of the tumor. A large tumor may cause loss of vision, particularly peripheral vision, if it compresses the optic chiasm (where the optic [eye] nerves come together, located above the pituitary gland).

Can a pituitary tumor cause excessive urination and thirst?

Occasionally a pituitary tumor causes diabetes insipidus, which results in frequent urination and excessive thirst. Diabetes insipidus is not high blood sugar levels; it is a problem with the ability of the kidney to retain fluid because of a deficiency of the pituitary hormone,…
