Hypocycloidal tomograms of the sella turcica and serum prolactin concentrations were obtained in 146 women with amenorrhea, galactorrhea, or both to diagnose prolactin-secreting pituitary adenomas. Findings suggesting an adenoma, ie, abnormal tomogram and elevated serum prolactin concentration, were found in 24.6% (16/65) of previously unscreened patients and 59.2% (48/81) of prescreened patients. The combination of an abnormal tomogram and elevated prolactin level was relatively specific for an adenoma, as 91% (42/46) of women with these findings who underwent surgery had histologically confirmed tumors. Tumors occurred in women from 15 to 45 years of age, with amenorrhea or galactorrhea ranging from less than six months to more than 20 years in duration. Some women in this series also had obesity, rapid weight loss, polycystic ovarian syndrome, amenorrhea following discontinuance of oral contraceptive use, or emotional stress.(JAMA 244:1329-1332, 1980)
