Pituitary adenomas are tumors that occur in the pituitary gland. Most pituitary tumors are benign, approximately 35% are invasive and just 0.1% to 0.2% are carcinomas. [1] Pituitary adenomas represent from 10% to 25% of all intracranial neoplasms, with an estimated prevalence rate in the general population of approximately 17%. [1] [2]
Pituitary tumor in MEN1 can be large and cause signs by compressing adjacent tissues. Pancreatic tumors associated with MEN-1 usually form in the beta cells of the islets of Langerhans, causing over-secretion of insulin, resulting in low blood glucose levels (hypoglycemia). However, many other tumors of the pancreatic Islets of Langerhans can ...
The tumor normally results in acral enlargement, arthropathy, hyperhidrosis, changes in facial features, soft tissue swelling, headaches, visual changes, or hypopituitarism. Since pharmacological therapy has had little effect on these tumors, a trans-sphenoidal surgery to remove part of the pituitary gland is the first treatment option. [5]
Visual acuity is reduced in half, and over 60% have a visual field defect. [2] [4] The visual loss depends on which part of the nerve is affected. If the part of the nerve between the eye and the chiasm is compressed, the result is vision loss in one eye. If the part after the chiasm is affected, visual loss on one side of the visual field ...
Multiple endocrine neoplasia (abbreviated MEN) is a condition which encompasses several distinct syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. In some cases, the tumors are malignant, in others, benign. Benign or malignant tumors of nonendocrine tissues occur as components of some of these tumor ...
A prolactinoma is a tumor of the pituitary gland that produces the hormone prolactin.It is the most common type of functioning pituitary tumor. [1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood (hyperprolactinemia), or due to pressure of the tumor on surrounding brain tissue and/or the optic nerves.
Hypophysectomy is the surgical removal of the hypophysis (pituitary gland). It is most commonly performed to treat tumors, especially craniopharyngioma tumors. [1] Sometimes it is used to treat Cushing's syndrome due to pituitary adenoma [2] or Simmond's disease [3] It is also applied in neurosciences (in experiments with lab animals) to understand the functioning of hypophysis.
Hypophysitis, inflammation of the pituitary gland. Autoimmune hypophysitis (or lymphocytic hypophysitis), inflammation of the pituitary gland due to autoimmunity. Nelson's syndrome, may occur after surgical removal of both adrenal glands, an out-dated method of treating Cushing's disease. Pituitary tumour, a tumor of the pituitary gland.
