A comminuted and minimally displaced fracture extends through the base of the odontoid process and body of C2 into the right lateral mass, involving the right transverse foramen. The left lateral mass is preserved. The tip of the odontoid process maintains its articulation with the anterior arch of C1. There is no retropulsed osseous component. No further cervical spine fracture is identified. Background diffuse osseous demineralization and multilevel degenerative change.
There is gross enlargement of the right thyroid lobe containing multiple nodules but no evidence of tracheal compression.
Unstable C2 fracture extending through the base of the odontoid, involving the body, right lateral mass and extending into the right sided neural foramen - a type 3 fracture. CTA is recommended to assess for possible vertebral artery injury.
