2. Nelson's syndrome - Wikipedia

   en.wikipedia.org/wiki/Nelson's_syndrome

   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. 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) and ...

3. Sheehan's syndrome - Wikipedia

   en.wikipedia.org/wiki/Sheehan's_syndrome

   Sheehan's syndrome, also known as postpartum pituitary gland necrosis, occurs when the pituitary gland is damaged due to significant blood loss and hypovolemic shock (ischemic necrosis) usually during or after childbirth leading to decreased functioning of the pituitary gland ( hypopituitarism ). [1] The pituitary gland is an endocrine organ ...

4. Cushing's disease - Wikipedia

   en.wikipedia.org/wiki/Cushing's_disease

   Endocrinology. Cushing's disease is one cause of Cushing's syndrome characterised by increased secretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary (secondary hypercortisolism ). This is most often as a result of a pituitary adenoma (specifically pituitary basophilism) or due to excess production of hypothalamus CRH ...

5. Pituitary adenoma - Wikipedia

   en.wikipedia.org/wiki/Pituitary_adenoma

   Pituitary adenoma. 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 and the estimated prevalence rate in the general population is approximately 17%.

6. Hyperpituitarism - Wikipedia

   en.wikipedia.org/wiki/Hyperpituitarism

   Hyperpituitarism is a condition due to the primary hypersecretion of pituitary hormones; [3] [medical citation needed] it typically results from a pituitary adenoma. In children with hyperpituitarism, disruption of growth regulation is rare, either because of hormone hypersecretion or because of manifestations caused by local compression of the ...

7. Pituitary disease - Wikipedia

   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.
