title: Common femoral vein thrombosis caused by a metal-on-metal hip arthroplasty-related pseudotumor.
abstract: We present a case of a pseudotumor causing a deep femoral vein thrombosis 16 months after undergoing a metal-on-metal total hip arthroplasty. There is increasing concern over the effect of metal ions that are produced by wear in metal-on-metal hip arthroplasty systems. Recently, a number of articles have reported the development of an inflammatory pseudotumor causing a number of different problems early on in the lifespan of the implant necessitating revision surgery. This case reports the first presentation of a pseudotumor causing a serious venous thrombosis due to pressure effect and indicates further possible evidence for caution when considering metal-on-metal bearing hip arthroplasty.
