Pituitary Tumor And Low Tsh
Could a pituitary tumor cause temporary one sided facial drooping without paralysis? Low TSH (normal T3 (liothyronine) & T4) Low ACTH. Waiting on more test results.
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
In hyperthyroidism, would a low TSH be caused by a pituatary tumor? If so, what would blood tests indicate?
Tumor forming TSH: TSH-secreting pituitary adenomas are benign tumors of the pituitary gland. They produce too much thyroid stimulating hormone (TSH) which causes the thyroid gland to enlarge and produce thyroid hormone in excess, leading to an overactive thyroid (hyperthyroidism) .most common initial therapy for patients with a TSH-secreting pituitary adenoma is transphenoidal resection of the tumour. ...Read more

Could a low TSH but normal Free T4 mean a Pituitary problem? Or would that be more indicative of the start of Hypothyroidism?
Sounds normal: Your description is consistent with normal thyroid function, but if you are concerned, you could provide exact numbers for us to review. ...Read more
With low TSH 0.02 but all normal thyroid and pituitary gland tests what could,be causing the suppressed tsh? Confused please help....
Does low TSH mean I have a problem with my pituitary gland ? Hypopituitarism? My free T3 (liothyronine) and T4 are high normal???
Could a low TSH (.28) & normal T3 (liothyronine) & T4 levels mean a Pituitary issue? Or is that more typical of hypothyroidism? Would high Chloride (111) effect it?
Means pituitary is: A TSH of 0.28 with normal free T4 and free T3 (liothyronine) likely means the pituitary is working properly. A TSH of 0.1-0.4 is lower than the reference range, which means about 2.5% of normal people have a TSH or 0.1-0.4. Thus, one hopes she is normal. Her endocrinologist can follow and recheck her levels in 4-6 weeks to confirm that her levels are stable (TSH not dropping lower; T4 or T3 (liothyronine) not above normal). ...Read moreSee 1 more doctor answer
What can cause low TSH of its not a Thyroid or pituitary problem? 0.01 TSH T3 (liothyronine) and T4 free normal, graves and hasmitos negative
2 possibilities: Hi. First of all, Hashimoto's doesn't cause a suppressed TSH, and YES, your TSH is SUPPRESSED, not "low", because your free T4 and total T3 (liothyronine) are "normal". A low TSH (pituitary defect) would cause low free T4 and possibly/probably low T3 (liothyronine). The most likely is a "hot" thyroid nodule (autonomously hyper-functioning); second most likely would be a phase of subacute thyroiditis. Follow over time to tell. ...Read more
What could cause hyperthyroidism if it's not graves, hasmitos, pituitary problem? I have low TSH 0.01 but normal free T3 (liothyronine) and T4 and normal total t3t4
Already answered: Hi. I already told you: hyper-functioning ("hot") thyroid nodule is most likely, but a phase of subacute thyroiditis (ST) is certainly a possibility. Following thyroid function over time, or a 123-I thyroid scan (and uptakes) would tell the difference. This all assumes you're not surreptitiously TAKING thyroid hormone (which would look like ST, but unlike ST would have a suppressed thyroglobulin). ...Read more
My FSH and LH levels were both super low at 0.1. But my estradiol was normal. Could this mean a pituitary tumor?
Not enough info: Can't answer your question from that information. LH/FSH varies during the cycle. Those values are a bit low even for the luteal phase. But what else is going on? Why was it done? Are you having normal cycles? Are you menstruating at all? Is your prolactin elevated? I assume you are not taking estrogens. Tiny pituitary tumors are common, and may not be significant. See your doctor. ...Read more
Low testosterone for past 14 years never investigated cause now looking for pituitary tumor. Is it possible after so long?
Yeah but not likely: pituitary tumors are not cancer. If they grow it is slowly. But the first thing they squeeze out are the pituitary cells controlling testosterone. More common is simply low testicular output. The pituitary levels of stimulation of testosterone are HIGH with that; low if pituitary tumor squeezing them out. simple blood test. ...Read more
LH and FSH normal at 2 range (2-9). Prolactin 18 high end of normal. Low T , low sperm count. That could be secondary hypogonadism or pituitary tumor?
Endocrinologist: If ur T is truly low, then FSH and LH should be towards the upper limit of normal (near 9); the fact that it is not could mean secondary hypogonadism, which has many causes (including a tumor). However, a brain tumor should cause some symptom eventually - headaches, vision trouble. U may need to just repeat the blood test to put ur mind at ease. Talk to an Endocrinologist w/ ur symptoms & lab resu ...Read more
