A Patient-Friendly Guide to Understanding Neck MRI Findings
If you’ve had a cervical spine (neck) MRI, you may have seen medical terms like herniation, stenosis, or spondylosis on your report. These words can feel overwhelming, leaving you unsure what they really mean.
This guide will help you make sense of the most common terms in plain language, so you can feel more confident when talking with your doctor or specialist.
Disc Bulge – The outer rim of the disc bulges outward, a little like an overinflated tire. In the neck, bulges may narrow the space for nerves and sometimes cause pain, tingling, or numbness in the arms.
Disc Protrusion / Herniation – The inner material pushes outward more prominently. In the cervical spine, this can pinch nerves that travel into the shoulder, arm, or hand. More information here – https://friscorehab.com/conditions/herniated-disc/
Extrusion – A more significant herniation where disc material extends further out. This may press on nerve roots or even the spinal cord.
Sequestration – A fragment of disc breaks off and separates from the main disc. Less common in the neck but possible.
Spondylosis – A general term for “wear and tear” arthritis in the spine.
Anterolisthesis / Retrolisthesis – One vertebra slipping slightly forward (antero) or backward (retro). Even small shifts in the neck can matter more than in the low back because the spinal cord is close by.
Kyphosis / Loss of Lordosis – Instead of the normal C-shaped curve, the neck looks straight (“military neck”) or even curved backward. This can reflect muscle spasm, degeneration, or posture changes.
Transitional Vertebrae / Block Vertebrae – Variations in anatomy where a vertebra looks different than usual or two vertebrae are fused. Often congenital.
Central Canal Stenosis – Narrowing of the spinal canal where the spinal cord passes. In the cervical spine, this can lead to myelopathy (spinal cord compression). Symptoms may include clumsiness, difficulty with balance, or hand weakness.
Foraminal Stenosis – Narrowing of the small openings (foramina) where nerves exit the spine. In the neck, this can cause arm pain, tingling, or numbness.
Cord Compression – A red-flag finding. Direct pressure on the spinal cord can affect both arms and legs.
Facet Arthropathy – Arthritis or degeneration of the small joints in the back of the spine. Can cause stiffness and local neck pain.
Uncovertebral Joint Hypertrophy – Unique to the cervical spine. Overgrowth of the uncinate processes can narrow the foramina and contribute to nerve compression.
Ligamentum Flavum Thickening – Thickening of this ligament inside the spine can contribute to stenosis.
Ossification of the Posterior Longitudinal Ligament (OPLL) – A condition where this ligament hardens or calcifies, potentially pressing on the spinal cord.
Cervical Ribs – Extra ribs extending from C7, found in less than 1% of people. Usually harmless, but in some cases can contribute to thoracic outlet syndrome (tingling, weakness, or circulation problems in the arm).
The Dens (Odontoid Process) – A peg-like part of C2 that helps your head rotate. MRIs may check for dens fractures (after trauma), congenital differences, or instability — especially in arthritis.
Atlantoaxial Instability (C1–C2) – Looseness or instability at the top of the neck, seen in trauma, rheumatoid arthritis, or congenital conditions.
Juvenile Rheumatoid Arthritis (JRA) – Though rare, JRA can affect the cervical spine, sometimes causing instability at C1–C2.
Cord Signal Change (Myelomalacia) – Bright spots inside the spinal cord on MRI, suggesting past injury, scarring, or compression.
Syrinx / Syringomyelia – A fluid-filled cavity inside the spinal cord. Rare, but important if reported.
Nerve Root Impingement – The MRI may specifically mention which nerve root is being pressed (e.g., “C6 nerve root compression”).
Chiari Malformation – The lower part of the brain extends slightly into the spinal canal. Sometimes picked up on cervical MRIs.
Hemangiomas – Benign “spots” of blood vessels inside vertebrae. Common and usually harmless.
Osteophytes (Bone Spurs) – Bony overgrowth from arthritis, sometimes pressing on nerves or the cord.
Modic Changes – Changes in the vertebral endplates (the bone near the disc), reflecting degeneration or inflammation.
MRI findings in the neck are taken seriously if they involve the spinal cord. Seek medical care promptly if you have:
Weakness in arms or legs
Trouble with balance or coordination
Loss of hand dexterity (dropping objects, buttoning shirts)
Numbness or tingling spreading into both arms or legs
Changes in bladder or bowel control
These may suggest cervical myelopathy, which requires timely evaluation.
A cervical MRI report may look intimidating, but most terms describe common changes related to aging, wear and tear, or arthritis. Not every finding means you’ll need surgery. Understanding the language can help you have a clearer, more productive conversation with your provider.
If you’re in the Frisco / North Dallas area and dealing with neck pain, tingling, or disc problems, our clinic offers non-surgical treatment options — including DRX9000 spinal decompression, therapy, and supportive care.
