A 30-year-old gentleman with long-standing pelvic pain and no history of trauma, initially evaluated by hip x-ray. Typical findings of CAM morphology is depicted by osseous bump on the superior femoral neck obliterating the femoro-acetabular sulcus, as a pistol grip appearance of the proximal femur. It is the most common cause of femoro-acetabular impingement in men.

Normally the head-neck junction should be concave superiorly, in cases of CAM morphology, it appears flat or convex and even "bumpy" in appearance.
