<unk> s are almost always benign. However, as with many brain tumors, their treatment can be difficult, and significant morbidities are associated with both the tumor and treatment. * Headache (obstructive hydrocephalus) * Hypersomnia * Myxedema * Postsurgical weight gain * Polydipsia * Polyuria (diabetes insipidus) * Vision loss (bitemporal hemianopia) * Vomiting * Often occurs after treatment * Growth hormone (GH) insufficiency, caused by the reduction in GH production - symptoms include: * Stunted growth and delayed puberty (in children) * General fatigue, loss of muscle mass and tone (in adults) * Pituitary insufficiency * Often occurs to some degree because<unk> s develop in the area of the pituitary stalk, which can affect the function of the pituitary gland and many other hormones * Reduction in prolactin production is very uncommon and occurs with severe pituitary insufficiency. * Large pituitary tumors can paradoxically elevate blood prolactin levels due to the "stalk effect". This elevation occurs as a result of the compression of the pituitary stalk, which interferes with the brain's control of prolactin production. * In premenopausal women, elevated prolactin can lead to reduction or loss of menstrual periods and/or breast milk production (galactorrhea). * With stalk effect, prolactin levels are usually only slightly elevated, as opposed to prolactinomas in which the prolactin level is usually very high. * Diabetes insipidus occurs due to the absence of a posterior pituitary hormone called antidiuretic hormone. Symptoms include: * Excessive thirst * Excessive urination * Adrenal insufficiency occurs because of a reduction in ACTH production, a reduction in cortisol. In severe cases, it can be fatal. Symptoms include: * Fatigue * Low blood pressure * Electrolyte abnormalities
