Abstract:
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.
