The location-based difference in appearance of fibrous dysplasia (FD) lesions. a Craniofacial FD demonstrates dense, sclerotic lesions (green arrow). b Lesions in the long bones and axial skeleton are typically lucent. There is a typical lesion in the proximal femur with characteristic lucent ground glass appearance and shepherd’s crook deformity (blue arrow). c Mixed radiolucent/lytic FD lesions in the skull
