What is the pituitary of microaroadenoma?
The microadenoma pituitary is a very small, non -companion tumor that is formed in the pituitary. It is medically defined as a weight that is less than about 1 centimeter (10 millimeters) in diameter, which increases slowly and does not lead to any risk of metastasion or spread, to other parts of the brain or body. While pituitary microadenomas are benign, they can still cause problems if they disrupt normal hormone production. Microadenoma can increase or change growth hormone levels, thyroid stimulating hormone (TSH) adrenocorticotropic hormone (ATCH) or prolactin. Symptoms may vary very much and occasionally threatening life, but early diagnosis and treatment of drugs or surgery can prevent most patients from suffering from major complications.
It is often difficult to find the basic cause for microadenoma pituitary gland. The main cause is most likely genetic factors, but doctors have not yet identified specific mutations or genetic formulas that lead tumors. MostPeople who receive pituitary gland are over 60 years. Women are a little more sensitive than men for reasons that are not entirely clear.
Some microadenomas do not change hormonal secretion, but still cause general symptoms such as headaches, visual impairment and nausea. The microadenoma pituitary that increases prolactin levels can cause erectile dysfunction in men, missing periods in women or overall infertility in both sexes. Excessive growth hormone production can lead to acromegaly, a chronic condition in which body tissues and bones grow uncontrollably and cause disfigurement. With serious adrenal and thyroid problems can occur in ATCH and TSH tumors.
diagnosis of pituitary microadenoma involves reviewing full medical and family history of the patient and performing a number of tests. Blood test can detect unusual hormonal activity and possible genetic abnormalities.Tumors can usually be seen in compute scans of tomography and other imaging tests, although a very small matter is sometimes needed by exploratory surgery. The treatment decision can be considered as soon as microadenoma is discovered and all symptoms have been identified.
Surgery to remove the pituitary of microadenoma is the treatment of choice in most cases, although this is not always possible due to overall health or specific conditions of patients. In addition, it is possible that the tumor can return after removal. If surgery is not recommended or ineffective, patients generally start with daily drug regime drugs that are designed to block specific hormones that are excessively excluded. Some people have to take medication for the rest of their lives to prevent symptoms of deterioration or return.
