title: Universal spondylodiscitis in a patient with erosive peripheral arthritis and apatite crystal deposition.
abstract: A patient with erosive peripheral arthritis in whom vasculitis and monoclonal IgG kappa paraprotein were associated with sacroiliitis and widespread destruction of intervertebral discs is reported. Crystals resembling apatite were identified in intervertebral disc material, and we postulate that the discitis was accelerated by apatite deposition. Our case illustrates a unique example of axial involvement in rapidly progressive joint disease.
