Patients with pituitary microadenomas are treated with medication and surgery. Pituitary microadenomas are usually not too large, not more than one centimeter in size, and have no significant compressive effect on the optic nerve optic cross, so drug therapy can be considered. Especially for prolactinomatous pituitary microadenomas, oral bromocriptine treatment is preferred. Usually, the patient’s condition can be well controlled by oral bromocriptine, and the serum lactogen can be decreased quickly, and the pituitary microadenoma will gradually shrink or stop growing, in which case it will be considered clinically cured. In the case of growth hormone or adrenal hormone pituitary microadenoma, surgery should be considered as a priority.
