Metallosis is an uncommon condition in which there is infiltration of periprosthetic soft tissues and bone by metallic debris resulting from wear of joint arthroplasties. It is often associated with significant osteolysis; therefore the identification of metallosis is an indication for revision arthroplasty. The radiographic, CT and MRI features of metallosis in a 63-year-old man who presented 16 years post-arthroplasty are described in this case report.
金属沉着病是一种罕见的病症，其中人工关节置换术磨损产生的金属碎屑会浸润假体周围的软组织和骨骼。它常与显著的骨质溶解相关；因此，金属沉着病的识别是进行关节置换翻修术的指征。本病例报告描述了一名63岁男性在关节置换术后16年出现的金属沉着病的影像学、CT和MRI特征。
