How to Explain These Cervical MRI Findings in Simple Terms
Your MRI shows wear-and-tear changes in your neck bones and joints, with arthritis in the small joints of your spine and significant narrowing of the left-sided openings where nerves exit at two levels—this narrowing is squeezing the nerves that go down your left arm.
Breaking Down Each Finding
Degenerative Changes at C5-C6
- What it means: The bones and discs between your 5th and 6th neck vertebrae show aging changes—like rust on a hinge
- Simple explanation: "The cushion between two bones in your neck has worn down over time, similar to how a car tire wears with use"
- Context: These changes are extremely common—studies show that 86-89% of people over 60 have disc degeneration visible on MRI, and many people with these findings have no symptoms at all 1, 2
Facet Arthropathy
- What it means: Arthritis in the small joints on the back of your spine
- Simple explanation: "The small joints that help your neck move have developed arthritis—like arthritis you might get in your fingers or knees, but in your neck"
- Clinical note: These are the joints that allow your neck to bend and twist; when they develop arthritis, they can become enlarged and contribute to nerve compression 1
Moderate to High-Grade Left Foraminal Narrowing at C5-C6 and C6-C7
- What it means: The openings (tunnels) where nerves exit your spinal cord on the left side are significantly narrowed at two levels
- Simple explanation: "Think of these openings like doorways for nerves leaving your spine to go to your arm. On your left side, at two levels, these doorways have become quite narrow—like trying to fit through a doorway that's partially blocked. This can pinch the nerves going to your left arm"
- Why this matters: This is the finding most likely to explain symptoms like pain, numbness, tingling, or weakness radiating down your left arm 1
Important Context About These Findings
Critical caveat: MRI findings in the neck are notorious for showing abnormalities in people without any symptoms. Research demonstrates that degenerative changes are commonly identified in patients over 30 years of age and correlate poorly with the presence of neck pain 1. In fact, approximately 65% of asymptomatic patients aged 50-59 will have radiographic evidence of significant cervical spine degeneration 1.
What matters most: The correlation between your specific symptoms (if you have arm pain, numbness, weakness on the left side) and these imaging findings—not just the presence of the findings themselves 1.
Clinical Significance
The foraminal narrowing is the most clinically relevant finding here, particularly if you're experiencing left arm symptoms. The narrowing results from a combination of the disc degeneration and the facet joint arthritis working together to reduce the space available for the nerve 1. Most cases of cervical radiculopathy (nerve compression causing arm symptoms) resolve spontaneously or with conservative treatment 1.
