软骨钙沉积症，即焦磷酸二氢钙(CPPD)结晶沉积病，具有一系列的临床表现，从没有症状到严重的破坏性关节病。我们最近治疗了一位在颞颌关节附近有CPPD沉积的患者，这是一个模拟腮腺肿瘤的病变。在偏光显微镜下，CPPD晶体呈微弱的正双折射。最常见的是X线表现为纤维软骨结构中无症状的沉积，尤其是膝关节半月板。另一种不太常见的表现是“假性”急性关节炎。很少发现联合破坏的情况。
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.
