Doctor insights on:
"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
Visual & endocrine: Any tumor of the pituitary may affect the optic nerve and produces visual disturbances. The endocrine symptoms depend on the cell type involved and if it makes a hormone. If the tumor does not make hormones it causes deficiency of thyroid, adrenal and gonadal hormones. Excess production of hormone may cause hyperthyroidism and cushing syndrome etc. ...Read more
Few symptoms.: Pituitary tumors are slow-growing and tend not to cause any acute symptoms, allowing them to grow to a relatively large size prior to their discovery. Furthermore, most do not cause hormonal problems, and the usual symptoms they cause (vision change, sometimes headache) are nonspecific and may be caused by a number of other conditions. ...Read more
If you had an intradural, extramedullary tumor at L4 of uncertain type and a pituitary tumor that has caused years of diagnostic confusion and multiple conflicting opinions, would you get biopsies?
Yes I would: Getting a biopsy done on this spinal tumor (or aim for complete excision, is possible) could help define the nature/type of this tumor and hence may also help in providing a reliable medical therapy in the future. ...Read more
Unknown.: There are malignant and non-malignant pituitary tumors, some that produce hormones, some that don't. Some cause problems because of their size and relationship to the optic chiasm and can cause visual problems and headaches. Causes of pituitary tumors are unknown. ...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
It depends.: Often a first step is tumor removal (and obtaining a biopsy specimen), now frequently performed as an endoscopic surgery through the sinuses, usually done by both an ENT surgeon and a neurosurgeon. Tumors which make pituitary hormones may shrink or stabilize with oral medication. Large or aggressive tumors may require targeted radiation therapy, e.g. Cyber knife, after (or instead of) surgery. ...Read more
Hormone imbalance: The pituitary is a gland that controls many of the hormones of the body. There can be serious imbalance of many of the body functions if the pituitary is damaged or removed. Hormone replacement therapy is necessary, and careful monitoring of hormone levels is necessary. However, this has now become routine and easy to monitor. A good endocrine specialist can easily develop a plan of management. ...Read more
