ResumoThe aim of our study was to describe the MR imaging findings in patients with rapidly destructive osteoarthritis of the hip.The key MR imaging features of rapidly destructive hip osteoarthritis include joint effusion (100%), bone marrow edemalike pattern in the femoral head and neck (100%) or acetabulum (83%) or both, femoral head flattening (92%), and cystlike subchondral defects (83%). Additional findings are low-signal-intensity lines (33%) in the femoral epiphysis, bandlike areas of low signal intensity in the upper pole of the femoral head (8%), and focal signal abnormalities in the adjacent soft tissues (33%) on short tau inversion recovery MR images, fat-suppressed T2-weighted MR images, and fat-suppressed gadolinium-enhanced T1-weighted MR images.
