Pseudogout is a disease of calcium pyrophosphate dehydrate (CPPD) deposition of joints. It occurs most often in the knee joint. We herein report an extremely rare case of pseudogout arising in the left temporomandibular joint. A 75-year-old female visited our hospital complaining of pain, crepitus and trismus in the left temporomandibular joint. CT and MR images showed irregular and destructive changes of articular surfaces, and a poorly defined peripheral soft tissue component. Excision of areticular capsule and condylectomy of the left temporomandibular joint were performed.
After 3 months of follow-up, pain, crepitus and trismus of the left temporomandibular joint disappeared.
