<unk> s are<unk> s that occur in the pituitary gland and account for about 10% of intracranial neoplasms. Pituitary adenomas are often remain undiagnosed. Small<unk> s are found in 6 to 24 percent of adults at autopsy.<unk> s arise within the anterior lobe (adenohypophysis) of the gland. They may be classified according to the size of the<unk>  and type of hormone secretion. Pituitary adenomas subtypes include corticotrophic, somatotrophic, thyrotrophic, gonadotrophic, and lactrotrophic adenomas. There are no established causes for<unk> s. Patients with<unk> s may progress to develop lethargy, headache, nausea, and vomiting. Common complications of pituitary adenoma include bitemporal hemianopia, anosmia, acromegaly, gigantism, and Cushing's syndrome. Prognosis is generally good, and approximately 18% of patients with macroadenoma require further treatment. Pharmacologic medical therapy is recommended among patients with prolactinoma, thyrotrophic, somatotrophic, and adrenocorticotropic adenomas. The transsphenoidal microsurgical approach is the mainstay of treatment for growth hormone producing adenomas, adrenocorticotropic hormone-(ACTH) producing adenomas, and macroadenomas.
