In a case of CPPD crystal deposition disease of the pseudorheumatoid type and of long duration, calcified constrictive pericarditis developed and was surgically treated. Analysis of the calcium deposit in the pericardium was carefully made by infrared absorption, x-ray diffraction, and thermogravimetry. It revealed that the deposit was composed of B-type carbonated apatite. Previously, both calcium pyrophosphate dihydrate (CPPD) and apatite crystals, either in the same place or in different tissues, have been reported in the same patient. These observations raise the possibility that the same metabolic error might lead to both types of crystal deposition.
在一例病程较长的类风湿样假性痛风性焦磷酸钙双水化物（CPPD）晶体沉积病患者中，发生了钙化性缩窄性心包炎并接受了手术治疗。通过红外吸收、X射线衍射和热重分析法对心包中的钙沉积物进行了仔细分析。结果显示，该沉积物由B型碳酸磷灰石组成。此前，曾有同一患者在同一部位或不同组织中同时出现CPPD和磷灰石晶体的报道。这些观察结果提示，相同的代谢错误可能导致这两种类型的晶体沉积。
