Overview

Laboratory findings consistent with the diagnosis of pituitary adenoma include elevated serum prolactin level and elevated or decreased serum levels of other pituitary hormones.

Laboratory Findings

Laboratory findings consistent with the diagnosis of pituitary adenoma include:

Elevated serum level of prolactin
Elevated or decreased serum level of adrenocorticotropic hormone (ACTH)
Elevated or decreased serum level of growth hormone (GH)
Elevated or decreased serum level of thyroid-stimulating hormone (TSH)
Elevated or decreased serum level of follicle-stimulating hormone (FSH)
Elevated or decreased serum level of luteinizing hormone (LH)

Some adenomas secrete more than one hormone, the most common combination being growth hormone and prolactin.

 ==Overview==
+Laboratory findings consistent with the [[diagnosis]] of pituitary adenoma include elevated [[serum]] [[prolactin]] level and elevated or decreased [[serum]] levels of other [[Pituitary hormone|pituitary hormones]].
-'''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.
+==Laboratory Findings==
-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.
+*Laboratory findings consistent with the [[diagnosis]] of pituitary adenoma include:
-==Lab tests==
-Tumors which cause visual difficulty are likely to be ''macroadenomata'' greater than 10 mm in diameter; tumors less than 10 mm are ''microadenomata''.
-Some tumors secrete more than one hormone, the most common combination being GH and prolactin.
-Prolactinomas are frequently diagnosed during pregnancy, when the [[hormone]] [[progesterone]] increases the tumor's growth rate.
-Headaches may be present. The diagnosis is confirmed by testing hormone levels, and by radiographic imaging of the pituitary (for example, by [[CT scan]] or [[MRI]]).
