There are mildly displaced fractures involving both the right and left posterior elements of C2, at the pars interarticularis, with extension into the posterior aspect of the foramen transversarium bilaterally. There is mild diastasis at the fracture site which extends to the articular surface of the lateral atlantoaxial joints bilaterally. No extension to the vertebral body or other fracture noted.
Given the transverse foramen involvement, a CT angiogram of the neck was recommended (not included) and showed a small mural injury of the transverse portion of the right vertebral artery at the level of the C2 fracture.
