الإجابة: B. Pituitary gland
Galactorrhoea + menstrual irregularity with raised prolactin, after pregnancy is excluded and the rest of the hormone profile (incl. TSH) is normal, points to a prolactinoma — the most common cause of hyperprolactinaemia. The lecture's work-up then images the pituitary (contrast MRI) to look for the adenoma. Adrenal, breast or thyroid imaging does not explain a high prolactin.

After pregnancy and TSH are excluded, the work-up images the pituitary (cranial contrast MRI) to rule out a pituitary adenoma such as a prolactinoma.

The milky discharge is the result of high prolactin (prolactin causes galactorrhea), so the breast is not where the cause lies.

Severe primary hypothyroidism can raise prolactin through TRH, but her other hormone tests, including the thyroid profile, are normal, so thyroid imaging does not explain it.
