Can you get rid of a cyst on the pituitary gland with medicine?

Only prolactinomas: A cystic lump seen in the pituitary region on a MRI scan may represent one of several different types of growths: a cystic pituitary adenoma, craniopharyngioma, rathke cleft cyst, or others that are less common. Of these different types of pituitary growths, only a specific type of pituitary adenoma that makes prolactin (i.e. Prolactinoma) responds to medication. The others need surgical therapy.
