Skull Base Tumors

Skull base tumors are abnormal growths that develop in the head. These tumors form inside the skull, or rarely, outside the skull.

The physician and providers at the Clinical Neuroscience Institute’s Tumor Center are specially trained in the treatment of skull base tumors. Our highly-qualified team is focused on the thorough, effective care of this condition, helping our patients live a comfortable, more active, healthier life.

What are Skull Base Tumors?

Skull base tumors are abnormal growths that form deep in the brain, behind the nose and eyes. These tumors either develop at the base of the skull or spread there from other areas of the body. Treatment of these tumors is a delicate matter, as they are in a difficult-to-access area, and develop near critical areas of the brain that control bodily functions. 

Depending on the exact nature and location of the tumor, symptoms may include:

  • Bloody nose
  • Double vision
  • Drooping eyelid
  • Facial twitching or numbness
  • Fluid build-up in the ear
  • Headache
  • Hearing loss
  • Imbalance
  • Inability to smell
  • Nasal congestion
  • Ringing in the ears
  • Vision loss

Diagnosing Skull Base Tumors

Your doctor will ask about your symptoms, medical history, and order certain tests to diagnose a skull base tumor.

Testing for skull base tumors include imaging tests such as magnetic resonance imaging (MRI), computed tomography (CT) scans, computed tomography angiography (CTA), and on occasion, positron emission tomography (PET) can help the specialist make a diagnosis by reviewing images of the inside of the brain.

Further testing may involve a biopsy of the affected area.
