Pituitary inflammation can be caused by autoimmunity or infection. Autoimmune pituitary inflammation is most commonly seen in women of childbearing age, where the pituitary lesions are diffuse and homogeneous, and the main symptom is increased urination, which may be accompanied by headache, breast milk spillage, amenorrhea, pituitary dysfunction, and saddle zone compression. Infectious pituitary inflammation is most often seen with viral infections and can present with symptoms such as headache, dysuria, and pituitary dysfunction. Since pituitary inflammation is an autoimmune inflammatory disease, treatment is mainly to fight autoimmune inflammation using glucocorticoids, and if the hormones are not effective, immune preparations can be added. If the patient has symptoms of persistent hormone deficiency, hormone replacement therapy can be supplemented. During the course of treatment, patients should have regular follow-up examinations to check their blood hormone levels and evaluate the efficacy of the medications under the guidance of their doctors.
