All imaged bones are abnormal with mixed sclerosis and lucency and remodelling. This is particularly evident at the left hip. Features are those of polyostotic fibrous dysplasia.
Fibrous dysplasia can be either monostotic (most commonly) or polyostotic. Polyostotic fibrous dysplasia occasionally occurs in association with cafe-au-lait spots on the skin (dark-pigmented, frecklelike lesions) and precocious puberty. This complex is called McCune-Albright syndrome.
