Giant cells tumor recurrence at the third lumbar vertebra.

Giant cell tumors (GCT) of the spine are rare. We report a case of (GCT) of the third lumbar vertebra revealed by left lumbar radiculopathic thigh pain in a 47 year old man. Imaging showed an osteolytic process invading the vertebral body, the posterior arch and compressing the dural sac left side. Neurological decompression was first performed including stabilization by an instrumented postero-lateral graft. A surgical biopsy was obtained at the same time to confirm the diagnosis. A secondary L2-L4 tumor curettage and graft procedure did not prevent, 5 years later, tumor recurrence. We believe that the simple tumor curettage is insufficient to prevent giant cell tumors recurrence.
