Computed tomography reconstruction artifact suggesting cervical spine subluxation

Area of Science:

• Radiology
• Trauma Imaging
• Spinal Injury Assessment

Background:

• Computed tomography (CT) is widely used in trauma centers for evaluating cervical spine injuries after blunt trauma.
• CT is sensitive for bone injuries but has limitations in detecting soft tissue damage, disc herniation, and instability.
• CT-generated artifact can potentially obscure or mimic pathological findings.

Observation:

• This case report details a patient where CT artifact mimicked traumatic subluxation of the cervical spine.
• The artifact presented a diagnostic challenge, potentially leading to misinterpretation of the cervical spine's stability.
• Recognition of artifact is crucial for accurate assessment in blunt cervical spine trauma.

Findings:

• CT scans are highly effective for detecting bone injuries in the cervical spine.
• CT has lower sensitivity for non-bony injuries such as ligamentous damage or disc herniation.
• CT artifact can create false positives, suggesting injuries like subluxation that are not present.

Implications:

• Clinicians must be vigilant in identifying and interpreting CT artifact in cervical spine trauma evaluations.
• Over-reliance on CT without considering its limitations can lead to misdiagnosis and inappropriate management.
• Awareness of potential CT artifact is essential for the accurate acute clearance of the cervical spine in trauma patients.
