Resumo
Ganglion cysts are rarely encountered in the temporoman dibular joint (TMJ). The etiology remains unclear; however, it may
arise from the myxoid degeneration of collagenous tissue of the
joint capsule after trauma. We report a case of ganglion cyst in a
66-year-old woman. On physical examination, the patient pre sented a well-demarcated, mobile, nodular lesion in the right TMJ
region. A computed tomography revealed a degenerative change
of the right condyle. Magnetic resonance imaging showed a rounded
hypodense mass related to temporomandibular articulation. Local
excision was performed, and histologic examination showed a mul tilocular cystic lesion surrounded by a fibrous connective tissue
wall without synovial cells. The cells in the lining of the wall were
negative for D2-40. Postoperative follow-up revealed no recur rence. The nonspecific clinical presentation and infrequent
involvement of ganglion cysts with TMJ make diagnosis a chal lenge. The definitive diagnosis should be made from results of the
histologic examination.
