2. Craniopharyngioma - Wikipedia

   en.wikipedia.org/wiki/Craniopharyngioma

   A craniopharyngioma is a rare type of brain tumor derived from pituitary gland embryonic tissue [1] that occurs most commonly in children, but also affects adults. It may present at any age, even in the prenatal and neonatal periods, but peak incidence rates are childhood-onset at 5–14 years and adult-onset at 50–74 years. [2]

3. Therapeutic ultrasound - Wikipedia

   en.wikipedia.org/wiki/Therapeutic_ultrasound

   Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.

4. Pituitary adenoma - Wikipedia

   en.wikipedia.org/wiki/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, with an estimated prevalence rate in the general population of approximately 17%. [1] [2]

5. Nelson's syndrome - Wikipedia

   en.wikipedia.org/wiki/Nelson's_syndrome

   Melson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat extreme slackness. [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 ...

6. Sheehan's syndrome - Wikipedia

   en.wikipedia.org/wiki/Sheehan's_syndrome

   In a study of 1,034 symptomatic adults, Sheehan's syndrome was found to be the sixth-most frequent etiology of growth hormone deficiency, being responsible for 3.1% of cases (versus 53.9% due to a pituitary tumor). [8] Additionally, it was found that the majority of women who experienced Sheehan syndrome gave birth at home rather than in a ...

7. Pituitary apoplexy - Wikipedia

   en.wikipedia.org/wiki/Pituitary_apoplexy

   The pituitary gland consists of two parts, the anterior (front) and posterior (back) pituitary. Both parts release hormones that control numerous other organs. In pituitary apoplexy, the main initial problem is a lack of secretion of adrenocorticotropic hormone (ACTH, corticotropin), which stimulates the secretion of cortisol by the adrenal ...
