Synovial chondromatosis or chondrometaplasia is a rare disease in which foci of cartilage may develop in the synovial membrane, usually of the large diarthroidal joints. However, the temporomandibular joint may be affected, with less than 15 such cases documented. It is the purpose of this presentation to define the radiologic findings in synovial chondromatosis of the temporomandibular joint, not previously recorded, which allow for definitive diagnosis. These radiologic findings are: 1) widening of the joint space; 2) limitation of motion; 3) irregularity of joint surfaces; 4) presence of calcified loos bodies (cartilage); and 5) sclerosis of the glenoid fossa and mandibular condyle.
滑膜软骨瘤病或软骨化生是一种罕见疾病，其中软骨灶可能在滑膜中形成，通常见于大的滑膜关节。然而，颞下颌关节也可能受累，记录在案的此类病例不到15例。本报告的目的是明确颞下颌关节滑膜软骨瘤病的影像学表现，这些表现此前未被记录，可用于明确诊断。这些影像学表现为：1）关节间隙增宽；2）活动受限；3）关节面不规则；4）存在钙化的游离体（软骨）；5）关节窝和下颌髁突硬化。
