[[Autopsy]] series have suggested that [[pituitary gland|pituitary]] incidentalomas may be quite common. It has been estimated that perhaps 10% of the adult population may harbor such [[endocrinology|endocrinologically]] inert lesions.<ref name="pmid8154641">{{cite journal|year=1994|title=Pituitary magnetic resonance imaging in normal human volunteers: occult adenomas in the general population|journal=Ann.
