51-year-old male. Right hip pain. Evaluate for AVN, labral path. ACETABULAR LABRUM: Intermediate signal abnormality in the anterior superior labrum consistent with degeneration. No discrete tear is evident.ARTICULAR CARTILAGE AND BONE: Abnormal low signal intensity involving the subchondral bone of the superior aspect of the right femoral head consistent with avascular necrosis. This avascular necrosis involves nearly the entire articular surface of the femoral head. There is adjacent edema in the femoral head extending into the neck and intertrochanteric region. No frank articular surface collapse of the right femoral head. There is also avascular necrosis of the left femoral head as seen on the large FOV images without frank articular collapse.SOFT TISSUES: No significant abnormality noted. ADDITIONAL
1. Avascular necrosis of the bilateral femoral heads without frank articular collapse. Large amount of associated edema in the right femoral head and neck.2. Degeneration of the right anterior superior labrum without a discrete tear.
