Pituitary microadenoma in the brain is usually seen mainly in neurosurgery, or if the local hospital has a more detailed division, in oncologic neurosurgery, but the majority of tertiary hospitals still have neurosurgery as the most common department. Occasionally, some patients go to obstetrics and gynecology or genitourinary medicine for some pituitary microadenoma or other symptoms, such as irregular menstruation or long-term infertility, but eventually a pituitary microadenoma is found, so they still have to go to neurosurgery. Some patients may go to endocrinology for hyperthyroidism, glucocorticoid overproduction, and so on. However, these tests need to be completed, and if pituitary microadenoma is identified, neurosurgery should be consulted, because not only medical medication but also surgical treatment is needed, and radiotherapy is needed after surgery depending on the type of pathology.
