Abstract | STUDY DESIGN: OBJECTIVE: To present a previously unreported cause for symptomatic synovial cysts of the lumbar spine. SUMMARY OF BACKGROUND DATA: METHODS: RESULTS: Histopathologic examination of each cyst showed a cyst wall of fibrous tissue with synovial lining, inflammation, and granulation tissue. Examination of the tissue under polarized light showed positively birefringent, short blunt crystals of calcium pyrophosphate dihydrate. CONCLUSIONS: In patients with a history of gout or pseudogout, a rare possibility of a synovial cyst should be considered in the differential diagnosis during investigation for the cause of neural compression resulting in sciatic syndrome.
