Prolactinomas are generally benign prolactin-secreting tumors and account for 40-66% of all pituitary adenomas. The vast majority are microadenomas (diameter < 1cm) and suppress the hypothalamic-pituitary gonadal hormonal axis, while 10% are macroadenomas (≥ 1cm) and may cause additional mass effects due to size. Age prevalence varies widely, but they are commonly found in women during childbearing years, in part due to development of menstrual irregularities. Despite their benign nature, if diagnosis is delayed bone loss and vertebral fractures can occur, and the loss of bone density can be permanent.

The prevalence of prolactinomas is reported to be between 35 to 50 per 100,000. They are most commonly seen in women (10:1 ratio female/male) and the usual age range is between 20 to 50 years of age. Dopamine originating in hypothalamic neurons is a principal inhibitory regulator of prolactin release by pituitary lactotrophs and this pathway is the basis of medical treatments. Fortunately, only a minority of microadenomas will continue to grow (< 10%) but early detection, monitoring and a management plan, which may be multidisciplinary, is required for good outcomes. Consider accessing expertise in endocrinology and radiology to ensure correct differential between prolactinoma and non-secreting pituitary adenoma as treatment for the latter is usually surgical, not medical.
Severe adverse effects of dopamine inhibitors are unusual but cabergoline may include compulsive behavior (e.g. excessive gambling) as well as cardiac valvular abnormalities at high doses
