Meningioma

A meningioma is a tumor that forms on the membranes surrounding the brain and spinal cord. Most meningiomas are slow-growing and non-cancerous, and some are found incidentally on imaging done for another reason.

Signs & Symptoms

Symptoms depend on the tumor’s size and location, and many small meningiomas cause no symptoms at all. When symptoms do occur, they can include:

  • Headaches that gradually worsen
  • Seizures
  • Vision changes
  • Gradual changes in memory, personality, or thinking

Causes & Risk Factors

The exact cause of most meningiomas isn’t fully understood. Known risk factors include prior radiation exposure and certain inherited genetic conditions.

Diagnosis

Diagnosis is made through a neurological exam and brain imaging, typically an MRI or CT scan.

Treatment Options

Some small, slow-growing meningiomas are simply monitored with periodic imaging. Others are treated with surgery, depending on size, location, and whether they’re causing symptoms.
