Brain Tumor” The pituitary gland is an important organ of the human body, which secretes a variety of endocrine hormones and maintains the normal physiological activities of the human body. Research has proved that every 4-5 people can be found to have abnormal pituitary gland by MRI. Although most of the pituitary abnormalities do not need treatment, pituitary tumor is definitely one of the brain tumors with high incidence rate. Pituitary tumors are benign tumors, and so many of its symptoms are often overlooked, while different types of pituitary tumors have different symptoms. Gigantism, acromegaly Growth hormone cell adenoma: this kind of pituitary tumor secretes too much growth hormone, and the underage patients will grow too fast and even develop into giants, with tall stature, thick hands and feet, and fat lips, etc. Adults who get the disease will mostly show acromegaly, such as facial changes, broad forehead, big tongue, big nose and thick lips, thick fingers and toes, rough skin, and numbness of hands and feet with a sense of distension; since these changes are very slow, it is difficult for family members to notice. As these changes are very slow, it is difficult for family members to notice, and only after a long time, or even after a few years or ten years, can they find the change of facial features; and a more direct way to determine the hypertrophy of the extremities is to pay attention to the number of shoes and socks to see if there is any increase in the number of shoes and socks all the time; and some patients have high blood sugar, high blood pressure, increase in the amount of food, and pigmentation of the skin, and so on. Heavy feeling of generalized weakness, headache and joint pain, and even combined with heart disease, colorectal cancer and so on. So this kind of acromegaly patients walk in the street, the appearance of the characteristics of the obvious, it is easy to be found by the doctor, “doctor” where the mystery. Third, amenorrhea, lactation, infertility Prolactin cell adenoma: this type of pituitary tumor secretes too much prolactin, manifested as hyperprolactinemia. Female patients can be detected at an early stage because high prolactin leads to menstrual disorders of different degrees, breast overflow (spontaneous milk flow from breasts or milk flow after touching breasts) in non-lactating women, and even amenorrhea, hair loss, weight gain, headache, decreased libido, etc. This kind of female patients often can’t conceive, so women who are infertile and combined with amenorrhea-lactation syndrome should be highly alert to the fact that they have amenorrhea-lactation syndrome. Therefore, women with infertility combined with “amenorrhea-lactation syndrome” should be highly alert to the possibility of pituitary tumor. Decreased libido and impotence. Compared with female patients, male pituitary tumor patients are often found late because there is no menstruation as a barometer, and decreased libido is mostly regarded as a result of work pressure and physical fatigue, which are mostly neglected and hard to be found at an early stage. Until the appearance of vision changes and other symptoms to go to the hospital, but the patients have some other details can be early to help diagnose: the reduction of body hair (beard, armpit hair, pubic hair sparse less), skin changes (thinning), male breast hyperplasia, nipple scratching, the serious genitals do not develop or atrophy and become smaller. Fifth, centripetal obesity, skin purple lines adrenocorticotropic hormone cell adenoma: this kind of pituitary tumor secretes excessive adrenocorticotropic hormone, manifested as centripetal obesity (body fat and thin limbs), full-moon face (face such as full-moon combined with acne, beard increase), buffalo back, abdominal and thigh skin with purple lines, increase in cui-lii hair, etc. In severe cases, amenorrhea, decreased libido, skin changes (thinning), male breast enlargement, itchy breast, severe genital non-development or shrinkage of small. Heavy amenorrhea, loss of libido, general weakness, osteoporosis, and even bedridden; some patients combined with hypertension, diabetes, etc., and difficult to control blood pressure and blood sugar. Some pituitary adenomas often do not have any manifestation in the early stage, but when the tumor grows to a certain degree and presses the optic nerve, visual field impairment will appear (unclear vision in one eye or both eyes, easy to hit the door frame, and in serious cases, it gradually develops to blindness). Visual field defects are often manifested as narrowing of vision range, usually the first manifestation of seeing red things, incomplete vision; later on, when the lesion increases in size and the compression is heavier, the defects can be expanded to bilateral temporal hemianopsia (incomplete vision in the direction of the corners of the eyes on both sides). If the disease is not treated in time, the visual field defect can be enlarged again and the visual acuity will be reduced, resulting in total blindness. Some pituitary tumors compress the posterior lobe of pituitary gland and stalk of pituitary gland, causing severe thirst, drinking more water, urinating more and getting up more at night. Headache, sudden vision loss and even blindness There is another serious situation of pituitary tumor, that is, pituitary tumor stroke (sudden bleeding of tumor), in which the patient will have sudden and severe headache, accompanied by vision loss, visual field loss, nausea and vomiting; in serious cases, the patient will be blind and comatose, etc., which requires urgent treatment. Experts remind: pituitary tumor is benign tumor, slow growth, it is not necessary to talk about the tumor, if you have the above performance, you need to be vigilant, you can go to the regular hospital to see, early diagnosis, correct treatment, as the way of diagnosis and treatment.
