Yes, this imaging is highly consistent with cervical radiculopathy explaining the patient's left arm pain and left hand numbness/tingling.
The C4-C5 level findings—specifically the left lateral recess mass effect and mild left foraminal narrowing from the disc-osteophyte complex—are the most likely anatomical explanation for this patient's left-sided radicular symptoms. 1
Clinical Correlation
The imaging demonstrates classic structural causes of cervical radiculopathy:
- C4-C5: Disc-osteophyte complex with uncovertebral osteophytes causing left lateral recess compression and mild left foraminal narrowing
- C5-C6: Shallow disc herniation with mild foraminal narrowing bilaterally
Cervical radiculopathy typically results from either soft lateral disc displacement or spondylosis with foraminal compromise caused by calcified disc, osteophyte, or both 1. Your patient has both mechanisms present.
Determining the Symptomatic Level
The left-sided symptoms (arm pain, hand numbness/tingling) correlate anatomically with:
- C4-C5 pathology would affect the C5 nerve root (shoulder/deltoid weakness, lateral arm pain)
- C5-C6 pathology would affect the C6 nerve root (wrist extension weakness, thumb/index finger numbness, radial forearm pain) or C7 nerve root (triceps weakness, middle finger numbness)
The specific dermatomal distribution of the hand numbness/tingling will help pinpoint which nerve root is symptomatic. However, the C4-C5 level shows more aggressive pathology with lateral recess mass effect on the left, making it the prime suspect.
Important Caveats
Multilevel radiculopathy is common—multiple nerve roots may be affected simultaneously 1. The C5-C6 level could be contributing, particularly if symptoms involve multiple dermatomes.
Imaging-clinical correlation is imperfect: MRI demonstrates frequent false-positive findings in asymptomatic patients, and detected abnormalities are not always associated with acute symptoms 2. The abnormal imaging level does not always correspond to the clinical examination level 2. This is why physical examination findings (specific dermatomal sensory loss, myotomal weakness, reflex changes) are critical to confirm which level is truly symptomatic.
Diagnostic Confirmation
Look for these specific examination findings:
- Spurling test (neck extension with rotation and axial compression toward symptomatic side)—reproduces radicular pain
- Shoulder abduction test—relief of symptoms with arm abduction suggests nerve root decompression
- Specific myotomal weakness: C5 (deltoid), C6 (wrist extensors), C7 (triceps)
- Dermatomal sensory loss: C5 (lateral shoulder), C6 (thumb/index), C7 (middle finger)
- Reflex changes: Diminished triceps reflex is the most common neurologic finding in cervical radiculopathy 3
Management Algorithm
Initial conservative management is appropriate for 4-6 weeks unless red flags or significant motor deficits are present 4, 3:
- Physical therapy (strengthening, stretching, potentially traction)
- NSAIDs and muscle relaxants
- Most cases (75-90%) improve spontaneously 5, 6
- Clinically significant motor deficits
- Debilitating pain resistant to conservative treatment after 4-6 weeks
- Progressive neurologic deterioration
Surgical options include anterior cervical decompression with fusion (ACDF) or posterior laminoforaminotomy, both with 80-90% success rates for arm pain relief 1, 4, 5.
Red Flags to Exclude
Before attributing symptoms solely to degenerative radiculopathy, ensure no:
- Myelopathy (gait instability, bowel/bladder dysfunction, hyperreflexia, Hoffman sign)—can coexist with radiculopathy 1
- Malignancy, infection, or fracture
- Dynamic cord compression (symptoms may worsen with neck flexion/extension not visible on neutral imaging) 8
The imaging findings are sufficient to explain the clinical presentation, but the diagnosis of cervical radiculopathy is ultimately clinical, confirmed by concordance between imaging pathology and examination findings 2, 3.
