Spinal tumors are growths in the spinal canal or within the vertebrae in your spine. It is a tumor that develops within the spinal cord or the covering of the spinal cord (dura). An organ that affects the vertebrae in the spine is a vertebral tumor.
A spinal cord tumor may be classified as one of three different types depending on where it occurs concerning the protective membranes.
The following are the main types of intradural tumors:
- Tumors intramedullary
- A tumor located outside the medulla
Diagnosis
The fact that spinal tumors aren’t ordinary and their symptoms closely resemble those of more common conditions sometimes causes them to be overlooked. Because of this, it is imperative that your doctor knows your complete medical history and performs both a general physical exam and a neurological exam.
If your doctor suspects the presence of a spinal tumor, these tests can help confirm the diagnosis and pinpoint where it is located:
- Image of the spine using magnetic resonance imaging (MRI). MRIs produce accurate pictures of your spine, spinal cord, and nerves using a strong magnetic field and radio waves. In most cases, MRI is the preferred method of diagnosing spinal cord tumors. You may be injected with a contrast agent, highlighting specific tissues and structures.
- MRI scanners can be claustrophobic, and their thumping sound can disturb some people. Most scanners come with earplugs for noise reduction, and some come with TVs or headphones. Ask your doctor about a mild sedative if you’re feeling anxious. You may need a general anesthetic in certain circumstances.
MRI scan
- CT stands for computed tomography. The spine is imaged using a narrow beam of radiation during this test. In some cases, contrast dye is injected into the spinal canal to make abnormal changes easier to spot. Spinal tumors are rarely diagnosed with a CT scan.
- The biopsy. Under a microscope, only a tiny sample of tissue (biopsy) can determine the type of spinal tumor. This information will help determine the appropriate treatment.
