Pituitary Adenoma

Pituitary Adenomas, mostly, are noncancerous tumors located in the pituitary gland which is located at the base of the brain.

If you are suffering from any cranial or brain conditions, we urge you to see our brain specialists at ONE® Brain & Spine Center® for consultation so we may help alleviate your pain and improve your quality of life. Call (949) 383-4190 to schedule an appointment.

The cause of pituitary adenomas are unknown. There appears to be a small percentage of reoccurances in families meaning pituitary adenomas are unlikely to be inherited.

If you have an pituitary adenoma, the most common symptoms that you will experience are:

  • Headaches
  • Random weight loss or gain
  • Nausea and vomiting
  • Impaired vision
  • Muscle weakness
  • Pituitary adenomas are diagnosed by gathering blood and urine samples to test for irregular levels of hormomes. Brain imaging procedures such as MRIs and CT scans are completed to clearly show the size and location of a tumor. A growth hormone supression test will also be conducted to look at levels of horomones. Vision tests are good indications of a pituitary adenoma that may be impairing vision.

    Magnetic Resonance Imaging (MRI) – MRI of the brain to confirm diagnosis and identify location of the tumor.
    Computerized Tomography (CT Scan)- Scans of the chest, abdomen, and pelvis to find the original tumor site.
    Biopsy- Minimally invasive nature of fine needle aspiration biopsy may be required to confirm to confirm the type of tumor.
    Spinal Tap- Lumbar puncture to get a sample of cerebrospinal fluid to healp diagnose serious infections.

    Each pituitary adenoma patient is distinct. Factors that impact the course of treatment and outcome are patient’s overall health condition, age, gender, tumor location and size. The best treatment for pituitary adenomas is surgical removal. At ONE® Brain & Spine Center® your Southern California neurosurgeon, Robert Louis, MD, performs minimally invasive procedure to surgically remove the tumor.

    Medication and radiation are other treatments to help contain tumor growth. Medication will contain the release of hormones from occuring while radiation will kill any remaining tumor cells.

    Minimally Invasive Surgical Treatments

    • Endoscopic Transsphenoidal Surgery- The endoscopic transsphenoidal surgical procedure uses a light called endoscope inserted into the nostril and sphenoid sinus to access and remove pituitary tumors. The term transsphenoidal literally means “through the sphenoid sinus.”
