We describe a patient who developed a mass extending into the pelvis, five years after a metal-on-polyethylene total hip arthroplasty (THA). The histological pattern of perivascular lymphocytic infiltrate and fibrinoid necrosis was more in keeping with a metal-on-metal bearing failure. The pseudotumour compressed the femoral vein causing a deep venous thrombosis.
我们描述了一名患者，在接受金属对聚乙烯全髋关节置换术（THA）五年后，出现了一个延伸至骨盆的肿块。血管周围淋巴细胞浸润和纤维蛋白样坏死的组织学模式更符合金属对金属轴承失效的情况。假肿瘤压迫股静脉，导致深静脉血栓形成。
