Meningioma Specialist
A meningioma is a tumor that emerges from one of the three meninges layers, or membranes, that surround and protect your brain and spinal cord. Meningioma is the most common type of tumor that forms in the head, accounting for approximately 30% of all brain tumors. Although most meningiomas are slow-growing and non-cancerous, they can interfere with normal brain function. At Advanced Brain & Spine in Centennial and Wheat Ridge, Colorado, Dr. Itay Melamed provides surgical treatment options for Denver-area patients with meningioma tumors.

Meningioma Q&A

by Itay Melamed, MD

What is meningioma?

Meningioma tumors are found in the protective membrane that covers your brain and spinal cord. Because meningiomas don’t arise from the brain itself, they aren’t technically considered brain tumors. They’re treated as brain tumors, however, because they often grow inward and push on the surface of your brain. They may also grow outward toward your skull, causing it to thicken.

Meningioma, which may also arise along your spine, grow slowly and may go undetected for many years. If it becomes larger, however, it can cause a range of significant and debilitating neurological symptoms, including:

  • Headaches that worsen over time
  • Weakness in an arm or leg
  • Vision problems, including blurred or double vision
  • Hearing loss or tinnitus (ringing in the ears)
  • Diminished sense of smell


Larger meningioma tumors can also cause personality changes, memory loss, or seizures.

What causes meningioma?

Researchers don’t know exactly what causes meningioma tumors to develop, but it’s estimated that between 40-80% of these types of tumors contain an abnormal chromosome 22.

Although no one knows how this abnormality occurs, what is known is that chromosome 22 plays a role in tumor suppression.

Risk factors that have been linked to the development of meningioma include:

  • Having previous radiation treatments for your head can increase your risk of developing meningioma.
  • These tumors are also more common in women, and have been linked to female hormones — researchers have noticed that meningioma sometimes grows faster during pregnancy.  

How is meningioma treated?

For patients with non-cancerous meningioma tumors that don’t cause any noticeable symptoms, a period of “watchful waiting,” or careful observation, is often the best course of action. This means having regular MRI or CT scans, and reporting any new symptoms without delay.

Symptomatic, malignant, or otherwise problematic meningioma tumors are generally treated with surgery, radiation, or both.

Tumors that aren’t in a position to be removed surgically may only receive radiation therapy; radiation is also used to help treat patients with malignant meningioma tumors or patients with tumors that can’t be completely removed during surgery.

Whenever possible, Dr. Melamed removes meningioma tumors using minimally invasive endoscopic surgery techniques. This type of brain surgery is performed with a smaller incision because it’s done with an endoscope or a small, telescope-like device equipped with a light and a high-resolution video camera that allows Dr. Melamed to access and easily navigate the treatment area.

Endoscopic brain surgery allows Dr. Melamed to better see the critical structures of your brain, and to work around corners and in places that were inaccessible with previous techniques.
