Diagnosis
Jefferson fracture
Sample Report
Comminuted four part C1 fracture (Jefferson fracture) extending into the transverse foramen on the left. Recommend neck CTA to assess for vascular injury.
Anterior dislocation of the left C1 lateral mass from the occipital condyle, widening of the atlantodental interval on the right, and slight asymmetric widening of the left C1-C2 articulation suggest ligamentous injury. Consider MRI for further evaluation.
Inferiorly displaced and distracted C6 spinous process fracture.
Possible mildly displaced right C7 transverse process fracture.
Minimally displaced fractures of the right styloid process and of the bony nasal septum, which can be further evaluated with a dedicated face CT.
