60-year-old woman with adverse local tissue reaction after resurfacing arthroplasty of left hip.
A and B, Matched coronal multiacquisition variable-resonance image combination selective (MAVRIC SL) inversion recovery (A) and 2D fast spin-echo (FSE) STIR (B) images. Extraarticular fluid collection (arrow, A) is seen adjacent to lateral aspect of greater trochanter in region of trochanteric bursa and is shown to communicate with hip joint on MAVRIC SL. Communication with hip is not seen on 2D FSE. Level of diagnostic confidence was 3 (diagnosis can be made on 2D FSE but is better seen on MAVRIC SL) for both reviewers. Patient subsequently underwent surgery. Necrosis and defect were identified in fascia lata and hip joint. Metallic debris and foreign body reaction were found in trochanteric bursa.
