What is Meningioma?

Meningiomas are mostly benign tumors that are seen in nearly every part of the nervous system. The tumors originate from stem cells, called arachnoid cap cells. Though generally benign. meningiomas can enlarge, be aggressive, and even invade the surrounding tissues.

Most patients harbor meningiomas that are found incidentally by their doctors. These tumors often need to be only followed by serial MRI scans. When meningiomas of the brain do enlarge, they can cause symptoms. The majority of these is headache. But, other symptoms may be seen like progressive weakness, seizures, personality changes, nausea/vomiting, or changes in vision.

Risk factors for these tumors can be caused by a variety of factors, including exposure to radiation such as x-rays, genetic syndromes, and having received radiation to the brain for other lesions.

When detected, meningiomas are usually observed if they do not cause any symptoms. If necessary, they can be treated through surgical resection, or partial removal of the brain tumor with postoperative radiation therapy. Pathological analysis of the removed tumor aids in prescribing further care after surgery.

If you or a loved one have been diagnosed with a meningioma, we can help to understand the surgical and nonsurgical options. Cutting-edge Gamma Knife or minimally invasive resection techniques are available. Dr. Gantwerker will be with you every step of the way.
