A case report: Bilateral reconstruction of C2 lateral masses with expandable titanium cages following axis (C2) solitary plasmacytoma resection with 2-year follow-up.

Background: Solitary plasmacytoma (SP) caused the collapse/destruction of the C2 vertebral body in a 78-year-old male. To provide sufficient posterior stabilization, the patient warranted lateral mass fusion to supplement the bilateral pedicle/screw rod instrumentation.

Case Description: A 78-year-old male presented with neck pain alone.
