46-year-old male with left hip pain with sitting and stairs for many years. Had 1 prior dislocation. There is a linear band of gadolinium that separates the anterosuperior labrum from the underlying acetabulum at approximately the 1 to 3 o'clock position. We see no fluid-filled articular cartilage defects. There is a dysplastic "bump" along the lateral aspect of the femoral head, as seen on prior radiographs, which results in an alpha angle of 65 degrees on MRI, which was previously measured at 70 degrees on prior radiographs. There is also slight prominence along the anterior aspect of the femoral head/neck junction with the borderline alpha angle of 55 degrees. The ligamentum teres appears intact. The sacroiliac joints are within normal limits. A similar morphology affects the right femoral head/neck as seen on the large field-of-view images. The imaged musculature is normal in appearance.
1. Tear of the left acetabular labrum.2. Mild CAM deformities as described above. Please refer to the CT examination report for additional measurements.
