Management of prolactinoma with cabergoline treatment in a pregnant woman during her entire pregnancy

Abstract

Management of prolactinoma in pregnancy is a big challenge for the treating obstetrician as prolactin levels are normally raised in pregnancy and this creates a possibility of missing the diagnosis of prolactinoma. Women with micro adenomas and intrasellar macro adenomas do not require serial magnetic resonance imaging (MRI) or visual field testing as required in macro adenomas with extrasellar extension. A strict and vigil monitoring during each trimester for any clinical signs and symptoms related to tumor will suffice for the diagnosis of enlarging prolactinoma and for any active intervention required thereof. Dopamine agonists are the first choice of drugs to treat these tumors during pregnancy. Cabergoline is reported to be more effective and better tolerated as compared to traditional bromocriptine, with minimal risk of spontaneous abortion, congenital malformations or menstrual abnormalities. We are reporting a patient with macro prolactinoma who was treated successfully throughout her pregnancy with cabergoline. We achieved a very good control of prolactinoma without any significant alteration of dose and also without any adverse effects. We convey that cabergoline can be a first choice drug to treat macro prolactinomas in pregnancy also.
