X-ray photograph taken at the first visit of our facility revealed polyethylene abrasion of the left artificial hip joint, and osteolysis of the left acetabulum and femur (Figure 1).
Comparison of X-ray findings at the initial diagnosis (a) and 1 year later (b). Calcification around the left hip prosthesis was observed. The arrowhead indicates niveau formation in the greater trochanter marrow cavity.

In addition, niveau formation suggesting fluid accumulation was observed in the greater trochanter hollowed due to bone lysis (Figure 2).
CT findings. Multiple calcified lesions and accumulated fluid in the capsule and in bursa were observed.
