Familial isolated pituitary adenoma (FIPA) is a term that is used to identify a condition that displays an autosomal dominant inheritance and is characterised by the presence of two or more related patients affected by adenomas of the pituitary gland only, with no other associated symptoms that occur in multiple endocrine neoplasia type 1 (MEN ...
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 ...
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.
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.
The initial symptoms of pituitary apoplexy are related to the increased pressure in and around the pituitary gland. The most common symptom, in over 95% of cases, is a sudden-onset headache located behind the eyes or around the temples. It is often associated with nausea and vomiting.
Autoimmune hypophysitis can lead to deficiencies in one or more pituitary hormones, causing central diabetes insipidus if the posterior pituitary gland is affected as well as central adrenal insufficiency and central hypothyroidism if the anterior pituitary gland is affected. [1] The symptoms depend on what part of the pituitary is affected.
Women’s bodies go through many changes in menopause and the years leading up to it, known as perimenopause. This natural step in the aging process marks the end of the reproductive years. In ...
Pituitary tumors often encroach upon the middle chiasm from below. Pituitary apoplexy is one of the few acute chiasmal syndromes. It can lead to sudden visual loss as the hemorrhagic adenoma rapidly enlarges. The embryonic remnants of Rathke's pouch may undergo neoplastic change called a craniopharyngioma. These tumors may develop at any time ...
