Acronyms: FD: Fibrous Dysplasia; ABC: Aneurysmal Bone Cyst Summary: Fibrous dysplasia (FD) of bone is an uncommon skeletal disorder with a broad spectrum of clinical expressions that affects primarily the craniofacial bones. It may be affected by the evolution of lesions over time and by the appearance of superimposed changes, such as aneurysmal bone cysts (ABCs). We describe an unusual case of a cranial ABC accuring after long evolution of fronto-parietal FD in 16 years old girl. She was operated successfully with total removing of the ABC.
