A 14-year-old girl complained of difficulty opening her mouth and clicking sounds in the bilateral temporomandibular joints. On magnetic resonance imaging, anterior displacement of the joint disk without reduction was seen in the bilateral temporomandibular joints. In addition, a cystic lesion （12×6mm） was detected on the outside of the right temporomandibular joint. The movement of synovial fluid between the cystic lesion and upper joint space was observed during mouth opening/closing. We diagnosed a synovial cyst concomitant with temporomandibular joint disorder. Although the patient required conservative treatment, her symptoms were not resolved. Future surgical treatment is under consideration.
