The clinical, pathologic, and radiologic features of pigmented villonodular synovitis of large synovial joints are presented. The typical plain-film presentation of this unusual entity is a noncalcified capsular soft-tissue mass of the knee, without bony abnormalities. When pigmented villonodular synovitis occurs in other joints, it is often accompanied by cystic bone erosions. This important radiographic finding might mislead one to an improper diagnosis of neoplasia or infection. This review reveals insufficient emphasis in the radiologic literature on the high incidence of bone lesions in joints affected by pigmented villonodular synovitis. A mechanism for the development of bone cysts is proposed. Clinical, pathologic, radiologic, and therapeutic considerations are discussed.
本文介绍了大关节色素沉着绒毛结节性滑膜炎的临床、病理及放射学特征。这种罕见疾病典型的平片表现为膝关节无钙化的关节囊软组织肿块,无骨质异常。当色素沉着绒毛结节性滑膜炎发生于其他关节时,常伴有囊性骨质侵蚀。这一重要的放射学表现可能会导致对肿瘤或感染的误诊。本综述显示,放射学文献对色素沉着绒毛结节性滑膜炎累及关节时骨病变的高发生率关注不足。本文提出了骨囊肿形成的机制,并讨论了临床、病理、放射学及治疗方面的考虑因素。
