Right hip pain Despite attempts to minimize the artifact, the examination is limited by susceptibility artifact due to the presence of a right total hip arthroplasty.There is no abnormal signal intensity within the surrounding pelvic musculature. There is more pronounced fatty atrophy of the right hip musculature when compared to the left. Examples of this include the obturator externus (series 4 image 19) and the gluteus medius (series 4 image 15). There is slightly increased signal intensity of the attachment of the gluteus medius tendon although the tendon itself appears intact.A small fluid collection is seen along the greater trochanter of the right hip which extends into the soft tissues beyond the gluteus maximus muscle. A similar but smaller collection is seen along the greater trochanter of the left hip.The marrow signal intensity of the bony pelvis is normal.
1. Limited examination secondary to susceptibility artifact from right hip arthroplasty.2. Small amount of fluid along the right greater trochanter may reflect a small bursal collection or may be postsurgical in nature given that it appears to extend beyond the gluteus maximus muscle.3. Mild fatty atrophy of the right hip musculature compared to the left although there is no abnormal signal intensity to suggest edema or inflammation.
