• Pituitary Tumors are approached by a team of surgeons composed of a Skull Based trained ENT surgeon and a Neurosurgeon.

• Patients are seen and evaluated by each member of the Pituitary Tumor Team, and their case is presented to the Eisenhower Brain Tumor Board for discussion.
  
  
• Pituitary tumors are approached using modern neurosurgical technologies:

1- Neuroendoscopy
2- Microneurosurgery
3- Micro-Doppler
4- Radiosurgery
5- Stereotactic Image Guidance

• Pituitary tumors account for about 10-25% of brain tumors.
  
  
• The mean age of patients with pituitary tumors is 20-50 years.
  
  
• Although symptoms largely depend on the type of the pituitary tumor, however, most patients present with headache.
  
  
• Female patients are typically afflicted with Prolactin or ACTH-secreting tumors and males with Growth hormone-secreting tumors.
  
  
• Depending on the different studies cited, pituitary tumors can be classified into three groups: benign, invasive adenoma, and carcinoma.
  
  
• Adenomas form the largest portion of pituitary tumors with an overall estimated prevalence of about 17%, but only a minority is symptomatic.

• Tumors less than 1 cm are classified as microadenoma and tumors equal or greater than 1 cm in size are called macroadenoma.  Macroadenoma have a higher probability of causing visual field defects due to pressing on optic chiasm.
  
  
• Prolactin-secreting tumors are the most common pituitary tumors and respond well to non-surgical/medical treatment.
