Moderate sized right hip joint effusion present. Segmental loss of normal intramedullary fat from subcapital to mid right femoral neck on T1W series, hardly visible on the T2W series, representing a fracture.
Adjacent muscle oedema in the medial aspect of the right obturator externus and adjacent hip adductors, also present in the gluteal muscles laterally, with subcutaneous oedema overlying the greater trochanter. No erosive arthropathy to suggest septic arthritis.
Conclusion:
Recent femoral neck fracture, in addition to known subacute left superior and inferior pubic rami fractures.
