Chondrocalcinosis, ie, calcium pyrophosphate dehydrate (CPPD) crystal deposition disease, has a spectrum of clinical manifestations ranging from an absence of symptoms to a severely destructive arthropathy. We recently treated a patient with CPPD deposition adjacent to the temporomandibular joint, which simulated a parotid tumor. The CPPD crystals are weakly positively birefringent under a polarizing microscope. Most frequently they are found roentgenographically as asymptomatic deposits in fibrocartilaginous structures, especially the knee meniscus. A less frequent manifestation is "pseudogout" acute arthritis. Rarely, joint destruction is found.
软骨钙质沉着症，即焦磷酸钙二水合物（CPPD）晶体沉积病，临床表现多样，从无症状到严重的破坏性关节病不等。我们最近治疗了一名患者，其颞下颌关节附近有CPPD沉积，形似腮腺肿瘤。CPPD晶体在偏振显微镜下呈弱阳性双折射。在X线片上，它们最常表现为纤维软骨结构中的无症状沉积物，尤其是膝关节半月板。较不常见的表现是“假痛风”急性关节炎。关节破坏很少见。
