39-year-old female with a history of ankylosing spondylitis and bilateral hips sclerosis presents with pain. RIGHT HIP:ACETABULAR LABRUM: Although this examination was not protocoled for evaluation of the acetabular labrum, there is increased signal abnormality traversing the superior acetabular labrum suggesting a tear (image 12:series 8).ARTICULAR CARTILAGE AND BONE: There is decreased signal abnormality within the superior acetabulum and femoral head/neck consistent with the findings of sclerosis on recent radiographs. There is linear decreased signal abnormality traversing the intertrochanteric region of the left femur which may reflect prior stress reaction. There is no increased signal abnormality on fluid sensitive sequences to suggest an acute process/acute stress reaction. There is subchondral cyst formation in the superior acetabulum likely degenerative in etiology.SOFT TISSUES: The musculature of the right hip is normal in appearance. ADDITIONAL
1. Sclerosis of the acetabulum and femoral head which appears to be degenerative in etiology. There is linear decreased signal abnormality in the intertrochanteric region of the femora, bilaterally, which may represent prior stress reaction, however, there is no increased signal abnormality to suggest an acute process/stress reaction.2. Bilateral joint effusions with foci of low intensity signal abnormality internally suggestive of a synovitis, left greater than right.3. Findings consistent with the stated history of ankylosing spondylitis.4. Other findings as described above.
