Epidemiologic analysis of incidental macroadenoma is limited to autopsy studies and case series. There are no published data about prevalence of incidental pituitary macroadenoma in living patients. The objective of this study was to determine the prevalence of incidental pituitary macroadenoma. It was designed as an observational study of cranial computed tomography reports. An urban department of veterans affairs medical center was used for the setting. The subject group consisted of 3,550 consecutive patients at the Cleveland Department of Veterans Affairs Medical Center from January 1993 to January 1996. Patients with known or suspected pituitary or parasellar disease were excluded. Cranial computed tomography reports were reviewed. Original films and medical charts of all patients with pituitary macroadenoma were reviewed. Seven patients with incidentally discovered pituitary macroadenoma that ranged from 1 cm to 2.5 cm were found; prevalence was 0.20% (95% confidence interval 0.05, 0.35%). Evidence of partial hypopituitarism was found in most patients. All patients had normal visual fields at initial examination despite the size of the tumor, but 1 of 4 had a field cut demonstrated by Goldmann perimetry. These data confirm that, although the prevalence of incidental pituitary macroadenoma is low, screening identified patients to detect deficiency of corticotropin, thyroid-stimulating hormone, and gonadotropins and to detect visual field defects is important.
