  2. Pathophysiology
    1. See Pituitary Gland
  3. Definition: Pituitary Adenoma
    1. Benign Pituitary Neoplasm
  4. Epidemiology
    1. Pituitary Adenomas account for 10-15% of all Intracranial Masses
    2. Prevalence: 77 per 100,000 persons
      1. Prevalence suspected to be much higher (May incidentally occur in as many as 20% of all patients)
  5. Types: Based on Hormone Secretion
    1. Prolactinoma (>40% of adenomas)
      1. Lactotroph cell adenoma with Hyperprolactinemia
      2. Presents with Galactorrhea and Gynecomastia
      3. Also suppresses LH secretion resulting in Erectile Dysfunction in men and Amenorrhea and Infertility in women
    2. Non-functioning Adenoma (>28% of adenomas)
      1. Findings are related to mass effect (Headache, Vision change) or Hypopituitarism
    3. Growth HormoneSecreting adenomas (11-13% of adenomas)
      1. Somatotroph cell adenoma with Gigantism (prior to Growth Plate closure) or Acromegaly (adults)
      2. Presents with hand/foot/Mandible hypertrophy, Fatigue, proximal Muscle Weakness, Hypertension, Cardiomegaly or LVH
    4. ACTH Secreting adenomas (1-2%)
      1. Corticotroph cell adenoma with increased ACTH and Cushing Disease
      2. Presents with proximal Muscle Weakness, striae, central Obesity, moon facies, Hypertension, Acne Vulgaris, Hyperglycemia
    5. TSH-Secreting Adenoma (rare)
      1. Thyrotroph cell adenoma with increased TSH and Hyperthyroidism
    6. LH or FSH Secreting tumor (rare)
      1. Gonadotroph cell adenoma typically results in no symptoms unless mass effect (Headache, Vision change) or Hypopituitarism
      2. However Prolactinomas do suppress LH secretion resulting in Hypogonadism
  6. Types: Based on size
    1. Microadenoma (<10 mm)
    2. Macroadenoma (10 mm or larger)
      1. Most likely to grow and manifest clinically
  7. Findings: Presentations
    1. Incidental finding on imaging (asymptomatic Pituitary Incidentaloma)
      1. Found in >10% of patients and Clinically Significant in 0.1% of patients
    2. Hormone increased secretion - typically only one of the following affected (see above)
      1. Prolactinoma (Hyperprolactinemia)
      2. Gigantism in children prior to Growth Plate fusion or Acromegaly in adults (increased Growth Hormone)
      3. Cushing Disease (increased ACTH)
      4. Central Hyperthyroidism (increased TSH, rare)
    3. Mass effect (delayed presentation, especially in non-functioning adenomas)
      1. Hypopituitarism (30% of Pituitary Adenomas)
      2. Headache

          1. Cranial Nerve III (Oculomotor Nerve)
          2. Cranial Nerve IV (Trochlear Nerve)
          3. Cranial Nerve VI (Abducens Nerve)
        3. Later expansion
          1. Cranial Nerve II (Optic Nerve)
  8. Labs: Initial
    1. Serum Prolactin
      1. Serum Prolactin 100-200 mcg/L is typical for most Prolactin-Secreting Pituitary Microadenomas
      2. Serum Prolactin >250 mcg/L is highly suggestive of Prolactinoma
      3. Serum Prolactin >500 mcg/L is highly suggestive of macroprolactinoma (Test Specificity 98%, but poorly sensitive)
      4. Very large macroadenomas (>3 cm) may give false negative Serum Prolactin (Hook effect)
        1. False Negatives (Hook effect) result if Prolactin detecting Antibody is saturated by very high Prolactin levels
    2. Insulin-like growth factor 1 (IGF-1)
    3. Leutenizing Hormone (LH)

Pituitary Neoplasms (C0032019)

Definition (MEDLINEPLUS)

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.

Pituitary tumors are common, but often they don't cause health problems. Most people with pituitary tumors never even know they have them. The most common type of pituitary tumor produces hormones and disrupts the balance of hormones in your body. This can cause endocrine diseases such as Cushing's syndrome and hyperthyroidism.

Symptoms of pituitary tumors include

  • Headaches
  • Vision problems
  • Nausea and vomiting
  • Problems caused by the production of too many hormones

Pituitary tumors are usually curable. Treatment is often surgery to remove the tumor. Other options include medicines, radiation therapy, and chemotherapy.
Definition (NCI_NCI-GLOSS) A tumor that forms in the pituitary gland. The pituitary is a pea-sized organ in the center of the brain above the back of the nose. It makes hormones that affect other glands and many body functions, especially growth. Most pituitary tumors are benign (not cancer).
Definition (NCI) A benign or malignant neoplasm affecting the pituitary gland. The vast majority are adenomas arising from the anterior lobe of the pituitary gland.
Definition (MSH) Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
Definition (CSP) new abnormal pituitary tissue that grows by excessive cellular division and proliferation more rapidly than normal and continues to grow after the stimuli that initiated the new growth cease.

Growth Hormone-Secreting Pituitary Adenoma (C0346302)

Definition (NCI) An adenoma of the anterior lobe of the pituitary gland that produces growth hormone. The vast majority of cases are hormonally functioning and are associated with either gigantism or acromegaly.

ACTH-Secreting Pituitary Adenoma (C1306214)

Definition (NCI) An adenoma of the pituitary gland that produces corticotropin. The vast majority of cases are associated with Cushing disease. Clinical manifestations include truncal obesity with thin extremities, thinning of the skin, osteoporosis, and a tendency to bruise easily. Silent or hormonally non-functioning ACTH producing adenomas have also been described. They produce symptoms of a mass-related lesion.
Definition (MSH) A pituitary adenoma which secretes ADRENOCORTICOTROPIN, leading to CUSHING DISEASE.
