Fibrous dysplasia may be localised to the single bone (monostotic form) or multiple bones (polyostotic form). About 25-30% of the facial dysplasia is associated with cranial or facial involvement. Imaging plays an important role in diagnosis and follow-up in the cases of cranio-facial fibrous dysplasia because of the anatomical complexity of the region. We have described herein a rare case of fibrous dyplasia involving naso-orbito-ethmoid region in radiological perspective.
