Understanding The Causes Of Your Intradural-Extramedullart Tumors

It is hard to pinpoint the causes of most spinal cord tumors, they may develop in nerve roots or inside the surface of the dura and be the outcome of exposure to certain chemicals. In some cases, genetic disorders such as neurofibromatosis 2 and von Hippel-Lindau disease may play a role, along with other defective genes. This form of this spinal tumor can be the result of a metastasis, a cancerous tumor that has spread from another part of the body. In other cases they can be benign and may be one of the following types.*

Meningioma– Form from meninges, the membrane that surrounds the spinal cord.
Schwannoma– Forms in the tissue that covers the nerves.
Neurofibromas– Forms in the tissue that covers the nerves, frequently found in the cervical area.

Diagnosing Your Intradural-Extramedullary Tumors

For any spinal cord tumor, the diagnosis begins with a full physical exam and review of your family’s medical history, looking to see if any relevant genetic disorders are present. One of our professional doctors here at NYSI may go over a list of possible symptoms that are related with intradural-extramedullary tumors. Some symptoms that you may experience are*:

Back pain that radiates throughout the body
Loss of sensitivity in your nerves
Loss of bowel or bladder function
Difficulty walking
Back pain that worsens at night
Muscle weakness, particularly in your arms or legs

During your exam it is likely your doctor will conduct a neurological exam as well, this may include tests to detect*:

Abnormal reflex responses
Muscle strength
Coordination
Nerve function

After one of our board-certified spine doctors conducts your exam they may require you to undergo one or multiple image tests, such as: X-rays, CT scans, or MRI’s (magnetic resonance imaging). These will help determine your tumors existence, size, and location among other specifics.*

Treatment Options For Your Intradural-Extramedullary Tumors

We have a variety of possible treatment options depending on your intradural-extramedullary tumor and how fast it’s growing, its size, and the severity of your symptoms. Another determining factor when choosing treatment is whether or not your tumor is benign or malignant (cancerous). Even benign tumors can be risky because they threaten you neurologically by causing compression to the spine.*

Here at NYSI, we provide you with comprehensive care from your initial diagnosis up until your recovery. One of the following treatment options may be recommended to you by one of our doctors.*

Observation– When tumors are discovered at an early stage and pose no risk or reveal any symptoms, your doctor may suggest closely monitoring it on a regular basis. If and when the intradural-extramedullary tumor begins to grow your case will be reassessed and a new treatment course will be presented.*
Radiation Therapy– This nonsurgical treatment option is used on patients when the entire tumor cannot be removed. It helps to destroy cancer cells and ultimately shrink the tumor, relieving symptoms.*
Spinal Surgery – This is typically the preferred treatment method when the tumor causes severe symptoms or continues to grow. The goal of surgery is to remove as much, if not all, of the tumor as possible.*
