57 year-old woman with history of right hip pain. Moderate to severe osteoarthritis affects the right hip with osteophyte formation and loss of the articular cartilage, particularly along the anterosuperior aspect of the joint. There are also subchondral cysts in the anterior aspect of the femoral head with surrounding edema and subchondral cysts in the anterior acetabulum. There is no joint effusion. Osteoarthritis also affects the left hip to a slightly lesser degree. Prominence of the anterior aspect of the femoral head/neck junction indicates cam deformity with an alpha angle of approximately 60 degrees. The remaining bone marrow signal intensity is within normal limits.Evaluation of the labrum is limited on this non-arthrogram study; however, irregularity and signal abnormality of the anterosuperior labrum suggests extensive tearing.Mild osteoarthritis affects the left sacroiliac joint. There is a small amount of free fluid in the pelvis.
Degenerative arthritic changes of the right hip as described above.
