Pregnancy After Bromocriptine-Induced Reduction of an Extrasellar Prolactin-Secreting Pituitary Macroadenoma

Abstract

In patients with a large prolactin-secreting pituitary adenoma, a marked reduction in tumor size may be achieved with bromocriptine therapy. However, before consideration of pregnancy, surgical removal of the lesion usually is advised. A 36-year-old woman with a large extrasellar pituitary macroadenoma was treated with bromocriptine, 10 mg/day, which resulted in dramatic reduction of the tumor mass. Subsequently, she became pregnant and drug therapy was maintained throughout gestation. This case illustrates the use of bromocriptine in the management of large prolactin-secreting pituitary tumors and the necessity for adequate radiologic follow-up.
