This is something to do with the presence of fat and fat is the primary substance in bone marrow.There is mild nonlinear elevated STIR signal in the acetabulum adjacent to the arthroplasty as well as in the intramedullary space of the femur just distal to the arthroplasty. This may be due to marrow regeneration near the arthroplasty.
I quote this only to emphasise the comment.This could also be due to loosening or motion in these areas.
Trochanteric bursitisThere is a minimal joint effusion near the arthroplasty. There is an unchanged small fluid collection posterior to left greater trochanter. This could be due to focal bursitis.
This seems to be saying that the finding of an effusion might indicate an infection and then to say that infection cannot be confirmed in an MRI. Very confusing!The finding could also be seen with infection (but) MRI cannot exclude infection this area. However, there was no uptake on the WBC scan previously.

I love it! You probably feel like you have a medical degree after all this! That is why you are going to get to the bottom of it and find the right answer/solution! 
Love Granny C. The voice of reason. Isn't she great, Belladonna?
