There are many conditions that involve the pituitary. They are
often referring to as pituitary disorders. Some conditions are referred
to as diseases or syndromes. Pituitary tumors are responsible for
a majority of hormone abnormalities involving the pituitary gland.
There are several terms for pituitary tumors.
- Adenoma is a medical term for pituitary tumor. You will often
see “pituitary adenoma” used in MRI’s and radiology
- Micro-adenoma is a pituitary tumor that is less than 10mm in

There are pituitary tumors that secrete hormones and some that do
- Secreting tumors result in: A Prolactinemia,
Acromegaly, and Cushing’s.
- Non-secreting tumors are: Null cell or non-functioning
describe adenomas that do not secrete a hormones. Craniopharyngiomas and Rathky’s Cleft

Other Conditions Involving The Pituitary Gland
- Pituitary Cysts
Pituitary adenomas are most common growths of the pituitary gland,
but cysts can form in the pituitary region also.
- Empty Sella
The empty sella is not a disease but rather an anatomical description
of the pocket
(the sella) in which the pituitary gland lies
- Infections and Inflammatory Conditions
Infections are a rare cause of pituitary disease.
- Non-pituitary Tumors in the Sella
Most pituitary gland tumors will be adenomas but in rare cases
other tumors may be found in or involving the gland.
Treatment of Pituitary Adenomas
The treatment plan will be specific for each tumor type, as well
as for each patient, and may include surgery, radiation, and/or
