Radiographs of two patients with saturnine gout (lead gout) demonstrated radio-opaque material which resembled milk of calcium within several joints. A histochemical examination of knee aspirate of one of the patients revealed a combination of monosodium urate and calcium pyrophosphate dihydrate. Subsequently, the authors suspected that the findings of intra-articular milk of calcium were due to the coexistence of saturnine gout and calcium pyrophosphate dihydrate deposition disease rather than intra-articular calcified tophus.
两名铅中毒性痛风（铅性痛风）患者的X光片显示，在多个关节内有类似钙乳的不透射线物质。对其中一名患者膝关节穿刺液进行的组织化学检查发现，存在尿酸钠和二水焦磷酸钙。随后，作者怀疑关节内钙乳的发现是由于铅中毒性痛风和二水焦磷酸钙沉积病并存，而非关节内钙化痛风石所致。
