Sphenoid Bone Fibrous Dysplasia Detected Incidentally on Bone Scintigraphy by the Contribution of SPECT/CT Hybrid Imaging.

ABSTRACT

Fibrous dysplasia (FD) is a benign fibroosseous bone disorder. It has poliostotic and monostotic patterns. Monostotic FD is frequently asymptomatic and is usually discovered incidentally by radiologic imaging performed for other reasons. Bone scintigraphy is valuable for identifying disease extent. Craniofacial FD (CFD) is a form of the disease where lesions are limited to contiguous bones of the craniofacial skeleton. We presented a case with monostotic CFD who was detected incidentally on bone scintigraphy single-photon emission computed tomography/computerized tomography while being investigated for inflammatory arthropaties.
