Calcified bodies may arise in a joint due to trauma, arthropathy resulting in joint destruction or synovial osteochondromatosis. These calcified loose bodies may pass into a popliteal cyst though posterior joint-bursal communications, or can arise in a popliteal cyst de novo on account of chondrometaplasia. A case history illustrates the differential diagnostic considerations. X-ray combined with ultrasound investigation will exclude soft tissue tumors and vascular lesions.
钙化体可能因创伤、导致关节破坏的关节病或滑膜骨软骨瘤病而出现在关节中。这些钙化的游离体可通过关节后囊的通道进入腘窝囊肿，或者由于软骨化生而在腘窝囊肿中新生。一个病例说明了鉴别诊断的要点。X线检查结合超声检查可排除软组织肿瘤和血管病变。
