  • Disorder of pituitary gland
  • Optic chiasm disorder assoc with pituitary disorder
  • Pituitary disorder, anterior
Clinical Information
  • Disorders involving either the adenohypophysis or the neurohypophysis. These diseases usually manifest as hypersecretion or hyposecretion of pituitary hormones. Neoplastic pituitary masses can also cause compression of the optic chiasm and other adjacent structures.
  • Disorders of the anterior or posterior pituitary gland which usually manifest as hypersecretion or hyposecretion of pituitary hormones.
  • Your pituitary gland is a pea-sized gland at the base of your brain. The pituitary is the "master control gland" - it makes hormones that affect growth and the functions of other glands in the body. With pituitary disorders, you often have too much or too little of one of your hormones. Injuries can cause pituitary disorders, but the most common cause is a pituitary tumor.
