right hip septic arthritis status post surgical drainage and IV antibiotics. There is a small amount of fluid signal intensity anterior to the right femoral head and deep to the the tensor fascia lata and iliopsoas muscles which demonstrates enhancement on postcontrast images which is compatible with postsurgical change. The right hip joint effusion seen on the previous study has resolved but there is persistent enhancement of the synovium which is not unexpected. There is high T2 and low T1 signal within the posterior acetabulum on the right which has not progressed in size since the previous exam, this area has abnormal enhancement on postcontrast images. Mild enhancement is also seen along the medial aspect of the right acetabulum and the lateral aspect of the obturator internus muscle although this has improved markedly compared to the prior exam.The remaining osseous structures are within normal limits for the patient's age.There is no pelvic free fluid. No evidence of bowel obstruction.
1.Resolution of the right hip effusion status post surgical drainage. There is persistent synovial enhancement which is not unexpected given the history of septic joint and surgical intervention.2.Osteomyelitis of the posterior right acetabulum appears similar to the previous exam, clinical correlation is needed as imaging finding may lag behind clinical response. 3.Edema and subperiosteal fluid medial to the acetabulum on the right have improved.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
