Background
The purpose of this educational exhibit is to present a review of the imaging characteristics of fibrous dysplasia and its associated clinical syndromes.

Educational Goals / Teaching Points
Review epidemiology, clinical presentation, pathology, subtypes and methods of diagnosis/imaging appearance on multiple modalities for diagnosis of fibrous dysplasia and its associated clinical syndromes.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Monostotic fibrous dysplasia, Polyostotic fibrous dysplasia, Mccune-Albright syndrome, Mazabraud syndrome, Rind Sign, Shepherd Crook Abnormality, Paget disease, Nonossifying fibroma, Osteofibrous dysplasia, Enchondromatosis

Conclusion
Fibrous dysplasia can present in multiple anatomic distributions in its monostotic and polyostotic forms. In this exhibit, we review its characteristic appearances on radiographs, CT, MRI, and nuclear medicine bone scan. Multiple important clinical syndromes associated with fibrous dysplasia and important mimickers of fibrous dysplasia are also reviewed.
