-The diagnosis is generally entertained either on the basis of visual difficulties arising from the compression of the [[optic nerve]] by the tumor, or on the basis of manifestations of excess hormone secretion: the specifics depend on the type of hormone. The specific area of the visual pathway at which compression by these tumours occurs is at the [[optic chiasma]].
+==[[Pituitary adenoma differential diagnosis|Differentiating Pituitary adenoma from other Diseases]]==
-The anatomy of this structure causes pressure on it to produce a defect in the temporal visual field on both sides, a condition called [[bitemporal hemianopsia|bitemporal hemianopia]].
+==[[Pituitary adenoma epidemiology and demographics|Epidemiology and Demographics]]==
-Tumors which cause visual difficulty are likely to be ''macroadenomata'' greater than 10 mm in diameter; tumors less than 10 mm are ''microadenomata''.
+==[[Pituitary adenoma risk factors|Risk Factors]]==
-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.
+==[[Pituitary adenoma natural history, complications, and prognosis|Natural History, Complications and Prognosis]]==
-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]]).

-Treatment options depend on the type of tumor and on its size:
+==Case Studies==
-* '''[[Prolactinoma]]s''' are most often treated with [[bromocriptine]] or more recently, [[cabergoline]] which, unlike bromocriptine, decreases tumor size as well as alleviates symptoms, both dopamine agonists, and followed by serial imaging to detect any increase in size. 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.
-* '''Thyrotrophic adenomas''' respond to [[Somatostatin|octreotide, a long-acting somatostatin analog]], in many but not all cases according to a review of the medical literature. Unlike prolactinomas, thyrotrophic adenomas characteristically respond poorly to dopamine agonist treatment.{{ref_label|thyrotrophic|1|a}}
