No Pituitary Gland And Small Adrenal Glands
Are the small vessels of the pituitary as susceptible to thrombosis as the vessels of the adrenal glands, or is adrenal insufficiency caused by thrombosis limited to adrenal glands only?
Adrenal hemmorrhage: Adrenal hemorrhage can occur for a variety of reasons, one of which is adrenal vein thrombosis. This usually occurs in complicated settings (cancer, hypercoag states). Hemorrhage can destroy the glands. This does not usually occur in the pituitary. Except for sheehan's syndrome: postpartum pituitary hemorrhage due to shock/bleeding in a susceptible pituitary (enlarged and ready for lactation). ...Read more
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
No: Hi. No, the pituitary controls the part of the adrenal cortex that makes cortisol, and is a secondary regulator of the part of the cortex that makes aldosterone. Cortisol does have influential effects on the adrenal medulla, so I guess you could say there are some downstream effects from the pituitary. ...Read more
Can you explain the regulation of adrenal cortex function by the way of the pituitary gland stimulation of the adrena?
Feedforward/feedback: Hi. Hypothalamus important, but to keep it simple, pituitary ACTH stimulates the adrenal cortex to make cortisol. Cortisol negatively feeds back to suppress pituitary ACTH. If cortisol falls or a big stress is encountered, ACTH goes up and stimulates more cortisol production. The pituitary "sees" the increase in cortisol, and cuts back on ACTH to keep cortisol in appropriate range. Diurnal pattern ...Read more
How to know either it's from adrenal or pituitary gland that cause my hypocortisolism MRI pituitary normal. Acth level low. H/o exogenous steroid 2010.
Stimulate adrenals: Have your doctor do an adrenal stimulation test to check your adrenal response. Acth levels are often inaccurate and frequently not diagnostic. If you're on cortisone replacement already, it doesn't make much difference what the cause is, however your pituitary function can be analyzed one hormone at a time. Check w/an endocrinologist. ...Read more
If a person had lymphoma in the pituitary gland causing hypophysitis and partial adrenal insufficiency, could it become stable or shrink when hydrocortisone started and grow if hydrocortisone stopped?
Lymphocytic h-itis?: You don't manage "lymphoma" just with hydrocortisone. If you are perhaps referring to lymphocytic hypophysitis, this is a different matter altogether; this is an autoimmune illness that can wax and wane and for which you need to be very closely followed. The picture you describe is in fact a good match for how lymphocytic hypophysitis might behave on glucocorticoid treatment. ...Read more
Usually no: Most of those are benign but it all depends on the context. Have you been diagnosed with cancer before? Anything else see in the scan? Any suspicious sign or symptom? Why was the scan done to begin with? I would suggest you discuss the report with the ordering doc and let him/her decide if further work up is indicated. Best to you. ...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
What does low density nodular thickening of both adrenal glands without suspicious enhancement, presumably on the basis of small adenomas mean on my c?
I have suppressed pituitary gland my nuts are small but my test level is fine but I can not get hard my sex drive is low is there a cure do I need trt?
I have all the symptoms of Cushing's Disease, but my MRI shows a small pituitary gland. If my pituitary gland is small, why do I have a buffalo hump?
Look like Cushing's: Cushing's is diagnosed by demonstrating inappropriately elevated cortisol with blood, urine and saliva tests. Although pituitary tumors are the most common cause, adrenal and other tumors can do this. However, many people look like they have Cushing's but don't; Many people with metabolic syndrome have a cushingoid appearance. See your Endocrinologist. ...Read more
After receiving an MRI to check for a pituitary gland tumor the technologist wrote in the report that it appears I may have hydrocephalus and possibly a small mass. If I truly have hydrocephalus would my symptoms be prominent. In other words, would I be h
Neurologist saw a small cyst on my pituitary gland. Can this cause nausea? Was told to return in 1 year for repeat MRI. No labs were done.
Nausea pit cyst: Not likely. Discuss with neuro.Get a more detailed answer ›
Hormone replacement: Yes, but you will need to be on hormone replacement. The two most critical hormones are cortisol (adrenal) and thyroid. Testosterone or estrogen may need replacement. If the posterior pituitary is removed, DDAVP (desmopressin) will need to be given to regulate water balance. Discuss with an endocrinologist. ...Read more
Pituitary "enlarged": You need a ct or MRI to see the pituitary. The pituitary normally enlarges during pregnancy and puberty. Hypothyroidism (high tsh) can make it enlarged. Bad stuff: tumors in the pituitary can develop, and they sometime secrete excess hormones, giving rise to many different disorders. Aneurisms, cysts, other things can happen, but all these are readily seen on mri. ...Read more
No left-right: Hi. The pituitary does have front-to-back anatomical/functional differences (adenohypophysis vs. Neurohypophysis), but NO left-to-right anatomical/functional distinction. ...Read more
Too much, too little: Hi. The anterior pituitary hormones are TSH, ACTH, GH, LH, FSH, Prolactin (PRL). Disease occurs when ANY of them are over-produced or under-produced, although the frequency of such disease states varies widely (although ALL said diseases are, at face value, uncommon). Famous ones are Cushing's, acromegaly, and prolactinoma. ...Read more
Hypopituitarism: Hypopituitarism is a condition in which the pituitary gland does not produce one or more of its hormones or not enough of them. This condition may occur because of disease in the pituitary or hypothalamus. When there is low or no production of all the pituitary hormones, the condition is called panhypopituitarism. This condition may affect either children or adults. ...Read more
Infrequently: Dwarfism results from any of over 200 different conditions. 70% of little people are classified as achondroplastic (short limbs, near normal torso/head size). This results from a genetic disorder of long bone growth. Proportionate dwarfism (body parts in proportion but small) may result from pituitary failure of growth hormone secretion. Short stature in healthy people is not abnormal. ...Read more
Pituitary surgery: It usually is not "dangerous" at all. Most neurosurgeons are able to perform this via intranasal route which limits adverse effects. ...Read more
Pituitary disease: The hypothalamus and pituitary work together to regulate many functions in the body, including hormonal regulation. Diseases can causes hormone deficiency or excess. Some of the hormones regulated are the thyroid, growth hormone, prolactin, (breastfeeding hormone) testosterone or estrogen, and cortisol. ...Read more
