  • Figure 1
    Admission cervical radiographs
     

    Frontal cervical radiograph. C1 and C2 vertebrae are obscured on this incidence by overlying occipital bone and mandible. No fracture is clearly visible.

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Lateral cervical radiograph showing fracture lines of posterior arch of C1 vertebra (arrow). The predental space (arrowhead) and prevertebral soft tissues are within normal limits.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Transoral view without significant external displacement of C1 lateral masses (arrows).

     
    Area of Interest: Neuroradiology spine; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 2
    Subsequent CT

    Transaxial non-enhanced CT slice at C1 level showing three fracture lines of anterior and posterior arches (arrows). Medial tubercles of lateral masses (insertion of transverse ligament) are intact.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 3
    MRI

    Transverse T2 weighted MRI confirms intact transverse ligament of C1 vertebra (arrow).
