Paraspinal calcinosis associated with progressive systemic sclerosis. Case report.

The authors describe a case of paraspinal calcinosis in a 65-year-old woman with progressive systemic sclerosis. Although calcinosis occurs in up to 27% of cases of progressive systemic sclerosis, symptomatic paraspinal calcinosis is extremely rare. In the case reported here, multiple cervical facet joints were compromised by progressive calcinosis, leading to glacial spinal instability. Internal fixation was indicated to correct the instability and decompress the spinal canal. Medical therapy was instituted to arrest or reverse the ongoing calcinosis.
