Adenomas exceeding 10 mm (0.39 in) in size are defined as macroadenomas, while those smaller than 10 mm (0.39 in) are referred to as microadenomas. Most pituitary adenomas are microadenomas and have an estimated prevalence of 16.7% (14.4% in autopsy studies and 22.5% in radiologic studies).
Endoscopic endonasal surgery is a minimally invasive technique used mainly in neurosurgery and otolaryngology.A neurosurgeon or an otolaryngologist, using an endoscope that is entered through the nose, fixes or removes brain defects or tumors in the anterior skull base.
While a plain X-ray of the bones surrounding the pituitary may reveal the presence of a large macroadenoma, small microadenomas will not be apparent. Magnetic resonance imaging ( MRI ) is the most sensitive test for detecting pituitary tumors and determining their size. [ 2 ]
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.

Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
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. Pituitary adenoma, a noncancerous tumor of the pituitary ...
The Brief Pain Inventory is a medical questionnaire used to measure pain, developed by the Pain Research Group of the WHO Collaborating Centre for Symptom Evaluation in Cancer Care. The Brief Pain Inventory (BPI) is widely used around the world today to help with measuring a patients' pain intensity and the amount of interference the pain has ...
