Pituitary Gland Infection
Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more
All endocrine organs: Those include the ovary, thyroid, breast, and adrenal gland to name a few. ...Read more
I doubt: That is has, or you would be dead and unable to ask this question. If your doctor has said that a portion of your pituitary isn't working properly, then ask him/her to explain. ...Read more
Hypophysectomy: If the pituitary is removed, then the hormones made by the pituitary need to be replaced. The most important are hormones that control the adrenals and thyroid. Sex hormones (estrogen-women, testosterone-men) should usually be replaced. GH is usually only replaced in young people. If the posterior pituitary is removed and you have diabetes insipidus, DDAVP (desmopressin) is needed. ...Read more
Negative feedback: The pituitary gland secretes many hormones and releasing factors, including growth hormone. Taking human growth hormone means that your internal servo control mechanism will be shut off. The pituitary cells will react as if they have made enough hormone, and so stop secreting. This may obligate you to continue replacement therapy, unless you already have a deficiency of growth hormone. ...Read more
Symptomatic?: Often, there are no symptoms or loss of pituitary function. with empty sella syndrome. Patients may have symptoms caused by partial or complete loss of pituitary gland function.Symptoms can include: erectile dysfunction.irreular menstration, headache, low sexual desire etc. See Dr. if symptomatic. ...Read more
Need more info: Why do you think you have an overactive pituitary? The pituitary gland makes various hormones that are essential for correct function of adrenals, thyroid, testicles, growth, there are particular rare disorders that can occur because of a tumor in the pituitary making excess hormone, but symptoms will depend on which hormone is being made. You need to see an endocrinologist to evaluate. ...Read more
Extremely rare: However, any cancer that isn't treated by surgery, radiation or chemotherapy will eventually kill the person who has it. A pituitary adenoma and a craniopharyngioma (a dangerous benign tumor that arises near the pituitary) are both to be distinguished from cancer but both need to be managed. ...Read more
Cancer?: Hi. Did your doctor tell you it's "cancer" or a "tumor"? The VAST majority of pituitary tumors are BENIGN, not cancer. Without a biopsy, no one can assume cancer. Talk with your doctor...this may not be anywhere near as bad as you think. On the other hand, if you do have cancer in the pituitary, it can be bad. Talk with your doctor; get the information. Good luck! ...Read more
Depends: A thorough evaluation is essential in properly diagnosing tumors of the pituitary gland. Consultation with a neurosurgeon and endocrinologist is usually recommended. Treatment options depend on tumor type and location. ...Read more
Lh (leutinizing hormone); fsh (follicular stim hormone); gh (growth hormone); TSH (thyroid stim hormone); acth (adrenocorticotropic hormone); prolactin. The posterior pituitary makes oxytocin and vasopressin.
Men have the same hormones in pituitary; just different responses from the gonads. ...Read more
Depends on the type: Most tumors of the pituitary gland (90%) are benign tumors. Cancers of the pituitary gland fall into two categories: metastatic and primary. Metastatic cancers can go to the pituitary.Prognosis is dependent on where the cancer came from (ie. Is it lung, breast or melanoma?). Pituitary carcinomas arise from the pituitary gland.Treatment is multimodal and involves surgery, radiation and chemotherapy. ...Read more
Not trauma: From your description, not clear what kind of tumor you possess, but tumors do not occur due to trauma. A variety of different pituitary lesions may spontaneously arise, and each may need a different approach, depending upon hormonal effect. Suggest you seek neurosurgical consultation regarding mass effect, and maybe endocrinologist to assess hormonal status. ...Read more
Adenoma: A pituitary protocol MRI is designed to evaluate the pituitary gland. It is used to assess for adenomas , cystic masses, mixed cystic and solid masses, and dural based lesions such as a meningioma. The morphology of the pituitary gland is also evaluated to rule out structural abnormalities. ...Read more
Probably: I assume you are referring to the area surrounding the pituitary. This is the sella turcica, the portion of bone which protects it. At the posterior (back) of the pituitary, there is also a "bright spot" which is part of normal pituitary tissue. There are two completely different tissue types that make up the pituitary and they look different on mri. ...Read more
Posterior Pituitary: The posterior pituitary has intrinsic high t1 signal. It's thought to reflect the high concentration of neurosecretory granules in the neurohypophysis (posterior pituitary which stores/releases oxytocin ; vasopressin produced in hypothalamus). Absence of the normal posterior pituitary bright spot should prompt a search for an ectopic posterior pituitary that has failed to migrate from hypothalamus. ...Read more
Many: Simplistically, the pituitary produces 6 hormones (fsh, lh, gh, tsh, acth, prolactin) which control hormone secretions from your thyroid, testicles or ovaries, adrenal, breast milk. A sign of a large pituitary tumor is loss of peripheral (sideway) vision, that is, when you look straight ahead, you cannot see what on your sides. Pituitary tumors are not cancerous, they are benign. ...Read more
What are long term effects of damage to the pituitary gland from chemotherapy in a male in his 60's?
Loss of hormones: One may lose control of thyroid & adrenal function. One may no longer secrete antidiuretic hormone with resultant diabetes insipidus. One may stop secreting growth hormone and if a male hormones that stimulate the production of testosterone.These hormones all contribute to organism homeostasis & metabolism. Medical treatment can compensate for their loss. ...Read more
If a person finds out that she has a tumor on the pituitary gland and is bleeding, what should she do?
What parts of the adrenal gland are controled by the pituitary gland? I read that there are three parts of the adrenal gland.
The adrenal: cortex, or outer portion, is mostly controlled by the pituitary, and predominately produces cortisone, aldosterone and some sex hormones. The inner portion, or medulla, is regulated by blood pressure, nervous stimulation, emotions, etc. and produces epinephrine, norepinephrine and some other lesser hormones. ...Read more
My sister had been diagnosed with enlargement if the pituitary gland and not cancerous. What does this meab? Is it dangerous?
Pituitary: There are many normal physiologic conditions that enlarge the pituitary. Pregnancy, lactation, hypothyroidism. Presumably your sister had a ct or mri. Did it show a tumor? Just enlargement? It would be important to have measurements of pituitary hormones to determine what the MRI means. Prolactin, tsh, ft4. Is she menstruating? Normal menses suggest normal pituitary. ...Read more
How serious is a small tumor on the pituitary gland? It is not cancerous. What are the chances of not being able to have kids?
It depends: It is great that the small pituitary tumor is not cancerous. As long as it is not growing, observation may be an option. Due to the position of the pituitary, it cangrow and interfer with your vision. It can also disturb all of the hormones in your body since it secretes the regulatory hormones for your thyroid, adrenal glands,and ovaries.If these are disrupted, it will make it hard to conceive. ...Read more
Can i survive w/o a pituitary gland when tumor was removed was told pituitary also non-residual...Now having major issues following surgery
You : You can live well without a pituitary gland. But you will need close monitoring for metabolic problems. You will need very close supervision both from your personal physician and from an excellent endocrinologist. Various hormones will need to be taken and adjusted from time to time. It will be hard, but doable. Best wishes. ...Read more
I have been trying to gwt pregnant for three years with no luck and found out I have a mask on my pituitary gland. Can i still get pregnant?
Yes, but get treated:
yes, you could still get pregnant, although it is much less likely. The majority of pituitary tumors secrete prolactin, which is a substance that causes lactation and inhibits (but does not prevent) fertility. This is why some people think you cannot get pregnant while you are breastfeeding. While pregnancy is still possible, it is less likely. ...Read more
