Cervical Spine Pathology in Children

Critical Red Flags and Life-Threatening Conditions

• Acute onset with severe pain in a child, even with current normal activity, may represent serious cervical spine pathology, including vertebral artery dissection, atlanto-axial subluxation, or occult trauma, and requires prompt medical evaluation 1, 2
• Children aged 7 years are at high risk for occult neck injuries, particularly if any trampoline use, sports activity, or unrecognized trauma occurred, and should be evaluated promptly 1, 2
• Vertebral artery dissection can present 12-24 hours after neck hyperextension/rotation injury and can cause intramural thrombus leading to vessel dissection and intracranial emboli, resulting in devastating neurologic complications including stroke 1, 2
• Atlanto-axial subluxation can occur in previously normal children from minor trauma and may present with torticollis or neck pain, requiring immediate imaging if suspected 1, 2
• Cervical spine injuries from hyperflexion/hyperextension can be catastrophic and require prompt evaluation and imaging 1, 2

Imaging Recommendations

• MRI cervical spine without contrast is the preferred imaging modality if any red flags are present or if clinical suspicion remains high, with 100% sensitivity for detecting osseous injury in children and the ability to detect vertebral artery dissection, ligamentous injury, epidural pathology, and spinal cord compression 3
• Plain radiographs have only 73-90% sensitivity for cervical spine injury in children and miss soft tissue pathology, and should not be used alone if serious pathology is suspected 3

Management Algorithm

• If red flags are present, immediate emergency department evaluation is required, with MRI cervical spine without contrast if necessary 3
• If no obvious red flags but history is concerning, same-day evaluation by a physician is recommended, with detailed neurologic examination and consideration of MRI if any abnormalities are found or high clinical suspicion 1, 2, 3
• If benign examination and low suspicion, conservative management with NSAIDs and close observation for development of red flags is recommended, with immediate return if fever develops, neurologic symptoms appear, or severe headache with photophobia 4

Critical Pitfalls to Avoid

• Do not assume all neck pain in children is benign, and do not rely on absence of reported trauma to exclude serious injury 1, 2
• Do not delay evaluation based on current activity level, as serious pathology can have delayed presentation 1, 2
• Do not use plain radiographs alone if serious pathology is suspected, as sensitivity is inadequate 3

Evaluation of Neck Stiffness in Pediatric Patients

Key Clinical Features and Management

• The absence of fever significantly reduces concern for infectious causes like meningitis or epidural abscess, according to the Journal of Infection 5
• The absence of pain with forward flexion is reassuring, as meningeal irritation typically causes pain with neck flexion rather than lateral rotation, as noted in the Journal of Infection 5
• The American College of Radiology recommends that immediate imaging is not indicated in cases of benign clinical presentation, instead suggesting conservative management 6, 7
• Analgesia with acetaminophen and/or NSAIDs is recommended if there are no contraindications, as suggested by the Journal of Clinical Oncology 8
• The development of red flags such as fever, altered mental status, severe headache with photophobia, pain with forward neck flexion, or neurological deficits requires urgent evaluation and imaging, according to the Journal of Infection 5 and the Journal of the American College of Radiology 6

Imaging Considerations

• MRI cervical spine without contrast is the preferred modality if imaging becomes necessary, as recommended by the Journal of the American College of Radiology 6, 7
• Plain radiographs have limited utility but may be considered for evaluating congenital abnormalities or osseous pathology, as noted by the Journal of the American College of Radiology 6
• CT is not recommended as first-line imaging for non-traumatic neck stiffness in children, according to the Journal of the American College of Radiology 6

Specific Considerations for Pediatric Patients

• Occult neck injuries can occur from trampoline use or sports activities, even without reported trauma, as reported in Pediatrics 9
• Any neck pain or torticollis after trampoline activity warrants prompt medical evaluation, as recommended by Pediatrics 9

Critical Pitfalls to Avoid

• The American Academy of Pediatrics, as cited in Pediatrics, advises against assuming all neck stiffness is benign and recommends careful history and examination to exclude serious pathology 9, 5
• The Journal of Infection recommends against relying on Kernig's or Brudzinski's signs to rule out serious infection, as they have poor sensitivity for meningitis 5
• The Journal of Infection advises against delaying antibiotics if meningitis is suspected, recommending empiric antibiotics immediately, even before imaging or lumbar puncture 5

Imaging and Red‑Flag Assessment for Unilateral Neck Stiffness in Children

Red‑Flag Clinical Indicators

• Fever in a child with unilateral neck stiffness raises suspicion for infectious etiologies such as epidural abscess, discitis, osteomyelitis, or retropharyngeal abscess. American College of Radiology recommends urgent evaluation when fever is present. 10
• Neurologic deficits (e.g., motor weakness, sensory changes, asymmetric reflexes, gait abnormalities) indicate possible nerve‑root or spinal‑cord compromise and constitute an emergency red flag. American College of Radiology advises immediate imaging. 10
• Persistent night‑time or constant neck pain lasting > 4 weeks is concerning for underlying malignancy and warrants further work‑up. American College of Radiology lists this as a critical warning sign. 10
• Unintentional weight loss or palpable lymphadenopathy suggest a neoplastic process and should prompt expedited diagnostic imaging. American College of Radiology includes these findings among red‑flag criteria. 10
• Tachycardia may reflect systemic infection or inflammatory disease and is considered a red flag that necessitates prompt imaging. American College of Radiology recommends evaluation. 10

Imaging Recommendations

• MRI of the cervical spine without contrast is the definitive imaging modality when any red flag is present, offering 100 % sensitivity for detecting osseous injury in children. This high sensitivity provides strong evidence for its use as first‑line imaging. American College of Radiology endorses this approach. 11
• MRI also provides superior detection of vertebral‑artery dissection, ligamentous injury, epidural pathology, spinal‑cord compression, and other soft‑tissue abnormalities compared with plain radiographs. The evidence supporting MRI’s comprehensive diagnostic capability is robust. American College of Radiology recommends MRI for these indications. 11
• Plain radiographs have limited diagnostic performance, with only 73‑90 % sensitivity for cervical‑spine injury in children and a high likelihood of missing soft‑tissue, vascular, and epidural pathology. Consequently, the American College of Radiology advises against relying on plain films when serious pathology is suspected. 11
• MRI provides direct visualization of the spinal cord, ligaments, and intervertebral discs—structures that plain radiographs cannot adequately assess—supporting its role as the preferred imaging study. American College of Radiology highlights this advantage. 10
