'''Pituitary adenomas''' are [[tumor]]s that occur in the [[pituitary gland]], and account for about 10% of intracranial [[neoplasia|neoplasms]]. They often remain undiagnosed, and small pituitary tumors are found in 6 to 24 percent of adults at autopsy.
Pituitary adenomas arise within the anterior lobe (adenohypophysis) of the gland . Tumors less than 1 cm are called micro adenomas. Clinical symptoms depend on whether the tumor is secreting or nonsecreting. Nonsecreting adenomas grow and compress adjacent structures, most commonly causing a bitemporal hemianopsia due to chiasmatic compression. Lateral extension into the cavernous sinuses can result in cranial nerve palsies.

Treatment where the tumor is large can be with [[radiation therapy]] or surgery, and patients generally respond well.  Efforts have been made to use a progesterone [[antagonist]] for the treatment of prolactinomas, but so far have not proved successful.
