Abstract
This chapter will primarily focus on the role of imaging in the evaluation of pituitary neoplasms (adenomas). Pituitary adenomas are usually benign indolent neoplasms. Although some may lead to symptoms due to hormonal hyperactivity with debilitating systemic consequences or from involvement of adjacent critical structures, many are asymptomatic and discovered incidentally. Adenomas arise from clonal mutations of somatic cells and their cause remains unknown. Oncogenes are not known to play a significant role in their genesis [1]. Definitive treatment involves any combination of medical and surgical intervention depending on the type of hormone they elaborate, their size, and local extent.
