“…On histopathological, synovial cells are D2-40 (podoplanin) positive; it can differentiate between synovial and ganglion cysts. 16,19 The lining cells of synovial cysts are predominantly type B (fibroblast-like) synovial cells, and the inflammatory components produced by the synovium in patients with chronic inflammatory and degenerative joint diseases are associated with synovial cysts. 2 Synovial cysts can be caused by herniation of the synovium into the surrounding tissue or the migration of synovial tissue during embryonic development.…”

BackgroundTMJ synovial cyst with few symptoms is rare. It was detected by magnetic resonance imaging (MRI); furthermore, we present the review that focused imaging findings.Case presentationA 48‐year‐old female complained TMJ discomfort during mouth opening. MRI showed a lesion that exhibited high signal intensity on T2‐weighted images behind the condylar head. The lesion was a cyst lined by synovial cells.ConclusionSynovial cysts frequently cause swelling and pain; however, some cases produce few symptoms. MRI is considered useful for diagnosing synovial cysts. All TMJ pathogenesis should be addressed during TMJ surgery to prevent recurrence of synovial cysts.
