Neurosurgery at Mercy - Baltimore, MD

Dr. Charles Park of The Minimally Invasive Brain and Spine Center in Baltimore, Maryland, works with patients to diagnose pituitary tumors and determine the most effective treatment options. 

About the Condition

A pituitary tumor is a mass of abnormal cells in the pituitary gland. The tumor causes the pituitary gland to produce too many or too few hormones. The pituitary gland is a pea-sized gland located at the base of the brain. Pituitary tumors, also known as pituitary adenomas, can be classified as:

  • Macroadenomas – 1 centimeter or larger
  • Microadenomas – less than 1 centimeter

Most pituitary tumors are noncancerous and do not spread to other areas of the body, but can still cause symptoms. A few common types of pituitary tumors include:

  • Adrenocorticotropic hormone-secreting (ACTH) tumors
  • Growth hormone-secreting tumors
  • Prolactin-secreting tumors
  • Thyroid-stimulating hormone-secreting tumors
