A 22-year-old woman had no menses since she discontinued the use of an
oral contraceptive one year ago. Galactorrhea has developed recently. Now she
wants to become pregnant. She takes no medications and has had no headaches,
visual loss, or decreased libido. Physical examination shows no abnormalities,
except for the bilateral breast discharge. A test for serum human chorionic
gonadotropin is negative, the thyrotropin level is normal, and the serum
prolactin level is 95 µg per liter. MRI reveals a mass, 3 mm in diameter, in
the anterior lobe of the pituitary. How should she be treated?
