Abnormal morphology of the acetabuli with over-coverage of both femoral heads. There is also bilateral coxa profunda as evident with the acetabular fossa (Figure B and C: dotted blue lines) medial to the ilioischial line (Figure B and C: yellow line). Overall imaging appearance is consistent with pincer type femoroacetabular impingement (AFI).
Two areas of impingement are present at the anterosuperior and inferomedial corners of the hip joints ( Figure B and C: asterisks and blue arrows) and more pronounced at inferomedial aspect of the hip joints.
Lateral projection of the right hip showed normal cutback at the femoral head-neck junction. (Figure C: dotted blue line and blue arrow).
