Skull Base Tumor Overview


Skull base tumors form under the brain at the bottom of the skull. The skull base is a highly complex structure in that every nerve in the body that carries signals to and from the brain crosses it. Tumors that develop in this area are near critical nerves and blood vessels of the brain, spinal cord, head and neck. These tumors can grow inside or outside the skull. Not all skull base tumors are malignant, but even benign tumors can cause symptoms that affect a patient’s well-being and should be treated accordingly.

Symptoms of skull base tumors

Symptoms vary widely from patient to patient depending on the size, location and type of tumor. Sometimes, symptoms do not become apparent until a tumor grows large enough to create pressure on vital brain structures. In general, however, here are some of the most common symptoms:

  • Headaches
  • Blurry or double vision
  • Hearing loss
  • Difficulty breathing
  • Difficulty swallowing
  • Altered sense of smell
