Calcium pyrophosphate dihydrate arthropathy with condylar destruction of the temporomandibular joint.

We report a case of calcium pyrophosphate dihydrate (CPPD) arthropathy with condylar destruction of the temporomandibular joint. Diagnosis was made on the basis of clinical findings and x-ray evidence of severe destruction of the condyle. The most likely diagnosis was considered to be neoplasm and a secondary infection of the left TMJ. Review of sections of the condyle taken at operation confirmed the diagnosis of left TMJ pseudogout. The postoperative course was uneventful with improvement in the clinical symptoms.
