Manage abnormal hormone levels [ 1] Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [ 2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.
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 ...
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%.
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 ...
Central nervous system (CNS) disorders or conditions may cause SIADH in 9% of cases, this includes subarachnoid hemorrhage (56% of CNS causes), pituitary surgery (35% of CNS causes), brain cancer, infections, stroke and head trauma. [2] No cause of inappropriate antidiuresis is initially found in 17-60% of cases. [2] A list of common causes is ...
Glucocorticoids. [2] Adrenocorticotropic hormone deficiency is a rare disorder characterized by secondary adrenal insufficiency with minimal or no cortisol production and normal pituitary hormone secretion apart from ACTH. [3] ACTH deficiency may be congenital or acquired, and its symptoms are clinically similar to those of glucocorticoid ...
Treatment of macroorchidism depends on pathogenesis. Surgical removal of the tumor is the most important and advised option for treating macroorchidism caused by non-functioning pituitary macroadenoma. [12] A non-functioning pituitary adenoma is a kind of benign tumor that does not secrete active hormones, and is from the pituitary gland. [13]
Scientists in South Africa have been stunned to discover that termite mounds that are still inhabited in an arid region of the country are more than 30,000 years old, meaning they are the oldest ...
