Craniopharyngioma is a rare, usually suprasellar [ 15] neoplasm, which may be cystic, that develops from nests of epithelium derived from Rathke's pouch. [ 16][ 17] Rathke's pouch is an embryonic precursor of the anterior pituitary. [citation needed] Craniopharyngiomas are typically very slow-growing tumors.
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%.
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 ...
A brain tumor occurs when abnormal cells form within the brain. [ 2] There are two main types of tumors: malignant (cancerous) tumors and benign (non-cancerous) tumors. [ 2] These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain ...
The National Cancer Institute estimated 22,070 new cases of primary brain cancer and 12,920 deaths due to the illness in the United States in 2009. The age-adjusted incidence rate is 6.4 per 100,000 per year, and the death rate is 4.3 per 100,000 per year. The lifetime risk of developing brain cancer for someone born today is 0.60%.

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 ...
Tooth resorption. Resorption of the root of the tooth, or root resorption, is the progressive loss of dentin and cementum by the action of odontoclasts. [4] Root resorption is a normal physiological process that occurs in the exfoliation of the primary dentition. However, pathological root resorption occurs in the permanent or secondary ...
