ABSTRACT
Pituitary tumors are frequently encountered intracranial neoplasms. They present with a variety of clinical manifestations that include symptoms and signs of excessive hormone secretion by the tumor, signs of hormone deficits by the normal pituitary gland and others related to expansion of the tumor mass and the resulting compression of surrounding structures such as the optic chiasm and cranial nerves. Advances in molecular biology, immunocytochemical staining and imaging, and the introduction of new treatment options have improved our understanding of the natural history of these adenomas and their management. Available treatments include surgical, medical and radiation therapy. Although the primary treatment for each tumor type may vary, it is important to consider all available options and select the most applicable for that patient. The interaction of all members of management team, including the primary care provider, the endocrinologist and the neurosurgeon in selecting the treatment course can only improve therapeutic outcome. Regardless of the initial choice of treatment,follow-up of all patients should be maintained indefinitely. The managing physician should be familiar with the natural history and long-term complications of pituitary adenomas, and with the side effects of treatments given over the years.
