The evaluation and management of subclinical pituitary disease.

Abstract

The advent of sophisticated and sensitive radiologic techniques has undoubtedly improved the evaluation of patients with established endocrine disease. An inevitable consequence of the increased sensitivity and widespread availability of modern imaging is, however, the discovery of apparently asymptomatic mass lesions in endocrine tissues. The clinician is then required to determine the appropriate degree of often uncomfortable and costly investigation in a patient with no overt disease. This article attempts to provide guidelines for the management of the 'pituitary incidentaloma', a pituitary mass lesion evident on a computed tomography or magnetic resonance imaging scan performed for a reason other than the evaluation of the pituitary gland.
