Abstract

Synovial cysts are found mainly in periarticular areas of the wrist, ankle, and knee, but also rarely in the temporomandibular joint (TMJ). Only 1 case of bilateral synovial cysts in the region of the TMJ has been reported. This case report described bilateral cysts in the TMJ in a 54-year-old Korean woman. T2-weighted magnetic resonance imaging (MRI) revealed bilateral oval cystic lesions lateral to the condylar capsule, whereas computed tomography (CT) apparently did not show the right hand side lesion. The cyst on the left side was surgically excised, and fine needle aspiration was performed on the right hand cyst. After 24 months, the long term follow-up showed no sign of recurrence.
