Neck Pain Radiating to Gluteal Area on Flexion
This presentation is highly atypical and requires immediate evaluation for serious spinal pathology—specifically, you must rule out cervical myelopathy with cord compression causing long tract signs, as neck pain does not follow typical dermatomal patterns to reach the gluteal region.
Critical Clinical Assessment
The radiation of neck pain to the gluteal area during neck flexion is a red flag that demands urgent investigation. This pattern suggests:
- Cervical myelopathy with spinal cord involvement causing descending tract dysfunction
- Possible dural tension affecting the entire spinal cord (Lhermitte's sign variant)
- Central cord pathology that may be causing bilateral lower extremity symptoms
- Rarely, inflammatory or infectious processes affecting multiple spinal levels
According to the 2025 ACR Appropriateness Criteria, "red flag" symptoms include spinal cord injury or deficit, which this presentation strongly suggests 1.
Immediate Evaluation Required
History Elements to Elicit:
- Myelopathic symptoms: Hand clumsiness, gait disturbance, bowel/bladder dysfunction, bilateral lower extremity weakness or numbness
- Constitutional symptoms: Fever, weight loss, night sweats (infection/malignancy)
- Inflammatory markers: History of autoimmune disease, recent infection
- Vascular risk factors: Sudden onset may indicate vascular etiology
Physical Examination Priorities:
- Upper motor neuron signs: Hyperreflexia, Babinski sign, clonus, spasticity
- Gait assessment: Wide-based, ataxic, or spastic gait patterns
- Hoffmann's sign and inverted radial reflex
- Sensory level testing from cervical through sacral dermatomes
- Lhermitte's sign: Electric shock sensation down spine with neck flexion
Imaging Algorithm
For this atypical presentation with suspected myelopathy, bypass plain radiographs and proceed directly to MRI.
First-Line Imaging:
MRI cervical spine without IV contrast is the most sensitive modality for soft tissue abnormalities and spinal cord pathology 1. While the ACR guidelines note MRI is not first-line for simple neck pain without red flags 1, your patient has a clear red flag (atypical radiation pattern suggesting cord involvement).
If MRI Contraindicated:
CT myelography cervical spine provides high spatial resolution imaging of the spinal cord and nerve roots 1.
Additional Imaging Considerations:
- MRI thoracic spine should be strongly considered given gluteal symptoms—the pathology may extend beyond the cervical region
- If vascular etiology suspected (sudden onset, risk factors): CTA neck 1
Common Pitfall to Avoid
Do not dismiss this as mechanical neck pain or cervical radiculopathy. Cervical radiculopathy follows specific dermatomal patterns (C5-T1) that do not include the gluteal region 1. The gluteal area is innervated by L4-S3 nerve roots—this distribution cannot be explained by isolated cervical pathology unless there is cord involvement affecting descending tracts.
Management Pending Imaging
- Avoid neck manipulation until myelopathy is excluded
- Urgent neurosurgical consultation if any myelopathic signs present on examination
- No cervical collar unless specifically indicated for instability
- Monitor for progression of neurological symptoms
Laboratory Workup:
Given the atypical presentation, obtain:
- CBC, ESR, CRP: Elevated inflammatory markers suggest infection or inflammatory arthritis 1
- Consider coagulation studies if vascular etiology suspected 1
Treatment Depends on Imaging Findings
Treatment cannot be recommended until the underlying pathology is identified through imaging. The differential includes:
- Cervical stenosis with myelopathy: May require surgical decompression
- Demyelinating disease: Requires neurology referral
- Spinal cord tumor or infection: Requires urgent specialist intervention
- Vascular malformation: May require neurosurgical or interventional management
This is not a case for conservative management with exercise therapy, NSAIDs, or physical therapy until serious pathology is excluded 2, 3.
