Multifocal Upper Cervical Spine Injury


CT – Sagittal reformatted image demonstrates precervical soft tissue swelling, type III odontoid fracture, inferior endplate fracture of C2, and widening of the posterior C2-C3 disc space.

MR – Sagittal T2 and IR images confirm the CT findings and also show anterior longitudinal ligament (atlantoaxial ligament), posterior longitudinal ligament (C2-C3) and posterior ligamentous complex (C1-C2 and C2-C3) injuries and disc separation at C2-C3.


Injuries of the cervicocranium are usually complex, involving multiple vector forces. Fractures of the dens are usually isolated although ~13% are associated with other cervical injuries (most often posterior arch of C1, extension teardrop, traumatic spondylolisthesis, atlantoaxial dissociation). Displaced type III odontoid fractures account for the “fat axis body” sign on lateral radiographs.
