Prolactin (PRL) secreting tumors are the most common functional neoplasms of the
pituitary and are commonly subdivided into microprolactinomas (<10 mm) and
macroprolactinomas (?10 mm) according to their baseline diameter. Patients with
prolactinoma present with symptoms evolving from hyperprolactinemia and with
those caused by pressure of the expanding mass on surrounding tissues, including
the optic chiasm and the cavernous sinuses. We hereby describe the possible
complications of macroprolactinomas, including mass effects, hypopituitarism, CSF
leak and apoplexy and discuss their relevant management. In general, all patients
harboring macroprolactinomas should be treated, the objectives being to achieve
normal or near normal PRL levels, to reduce or stabilize adenoma size and to
recover altered pituitary axes. Medical therapy with dopamine agonists (DA) is
the preferred initial treatment for the vast majority of patients harboring
prolactinomas. Pituitary surgery is indicated in patients who cannot tolerate or
are resistant to therapy with DAs, patients that seek fertility and harbor
adenomas that impinge on the optic chiasm, psychiatric patients with
contraindication to DA treatment and patients presenting with pituitary apoplexy
or a cerebrospinal fluid (CSF) leak. In addition, in this review, several patient
populations with unique clinical characteristics will be discussed separately
namely postmenopausal women, the elderly, children and patients with pituitary
carcinoma.
