临床上假痛风综合征患者,可呈现为急性疼痛的关节炎,也可呈现为慢性复发性游走性关节病,后者可造成膝、腕、肘、髋和其他关节的进行性破坏。常见于60岁以上患者,女性较多见。有人认为膝关节常受犯,而腕和手次之,但作者报告了三例患者为腕关节受犯。补偿偏光显微镜发现抽吸出的滑膜液中有二水焦磷酸钙结晶(CPPD)和X 线发现膝、腕和耻骨联合的关节软骨钙化,可以确定诊断。当然,仅关节软骨钙化一项,是有助于诊断的,但为非特异者。腕关节的三角纤维软骨为最早和常发生钙化的部位,其钙化可以是线状、点状或不定形的。
Clinically, patients with pseudogout syndrome may present with acute pain arthritis, or may present with chronic recurrent gonad arthropathy, which can cause progressive destruction of the knee, wrist, elbow, hip, and other joints. Common in patients over the age of 60, women are more common. Some people think that knee joints are often guilty, while wrists and hands are second to none, but the authors reported three cases of wrist injuries. Compensatory polarizing microscopy revealed that calcium phosphate pyrophosphate crystals (CPPD) and x-rays were found in the synovial fluid pumped out, and calcification of the articular cartilage in the knee, wrist, and pubic symphysis was diagnosed. Of course, calcification of articular cartilage alone is helpful for diagnosis, but it is non-specific. The triangular fibrocartilage of the wrist joint is the earliest and frequently calcified site, and the calcification may be linear, punctate, or indeterminate.
