WebbMacroprolactin; A Frequent Cause of Misdiagnosed Hyperprolactinemia in Clinical Practice Introduction Human prolactin (PRL) is a hormone secreted by the anterior pituitary lactotropic cells. Like any other anterior pituitary hormone, secretion of PRL also falls under hypothalamic control. WebbThe most common cause of hyperprolactinemia is a prolactinoma, a benign (noncancerous) prolactin-releasing tumor. Prolactinoma rates are about 30 per 100,000 in people assigned female at birth and 10 per 100,000 in people assigned male at birth. What is the difference between hyperprolactinemia and prolactinoma?
Webb14 jan. 2024 · Elevated levels of prolactin can also be a sign of a prolactinoma, a benign tumor in the pituitary gland. Prolactinomas release high levels of prolactin into the blood. In general, larger tumors cause higher levels of prolactin. An imaging test, such as an MRI, is needed to confirm if a prolactinoma is present.
