The most valuable auxiliary examination for hyperprolactinemia

What are the most valuable auxiliary examinations for hyperprolactinemia? Hyperprolactinemia is the most common pituitary disease, with galactorrhea and hypogonadism as prominent manifestations. Auxiliary examinations for hyperprolactinemia are of great significance for diagnosing the disease. So, what are the most valuable auxiliary examinations?

1. Physical examination. Pay attention to vision, fingertips abnormalities, obesity, hypertension, hirsutism, and chest wall lesions. Pay attention to genital development, atrophy, or pelvic mass during pelvic examination. Pay attention to galactorrhea, whether it is unilateral or bilateral, milk properties, and milk secretion during breast examination. Fat droplets can be seen in the collected milk under a low-power microscope.

2. Blood PRL level measurement The best time to collect blood is between 9 and 11 am in a quiet state. PRL is greater than 25up/L, which is high PRL. If the PRL value is greater than 50ug/L, the incidence of pituitary microadenoma is about 25%. When PRL is greater than 250up/L, the possibility of pituitary macroadenoma is high.

3. Imaging examinations Enhanced magnetic resonance imaging and enhanced computed tomography can be used to detect pituitary microadenomas. 1. Visual field examination Pituitary tumors can invade or compress the optic chiasm, resulting in visual field defects. Visual field defects can range from classic, complete bitemporal hemianopsia to small, partial quadrant defects or scotomas.

2. Gynecological ultrasound is used to observe the uterine shape, size and ovarian abnormalities. 1. If PRL is found to be slightly elevated, a blood sample needs to be collected and repeated to confirm the result.

3. MRL is suitable for patients with elevated PRL, even those with mild elevation.

Because MEL can help make an early diagnosis, visual field examination does not need to be routine.

4. If the breast milk is bloody, the patient should be referred to the breast department for treatment.

The above is an introduction to the most valuable auxiliary examinations for hyperprolactinemia. I hope it will be helpful to you.
