Patient Data

Age: 50 years
Gender: Female


Large left temporomandibular joint effusion with multiple small foci of low signal predominantly within the posterior joint recess suggestive of cartiliginous bodies. The disc is abnormal with loss of biconcavity, thinning of the anterior band and abnormal signal intensity. The disc overlies the mandibular condyle, with normal anterior translation of the disc and mandibular condyle to the articular eminence on mouth opening. Mandibular condyle maintains a rounded contour. Findings are suggestive of left TMJ synovial chondromatosis.
