Fig. 1 Coronal short tau inversion recovery (STIR) magnetic resonance image acquired with use of metal artifact reduction sequence (MARS), demonstrating a large pseudotumor (arrows) surrounding the prosthetic hip joint, approximately twenty-one months following total hip arthroplasty (Case 3). As a reference, the greater trochanter (GT), modular prosthetic femoral neck (N), and modular femoral head (H) are labeled.
