Abstract
Objective To investigate and analyze the imaging performance of SPECT and X-ray in fibrous dysplasia of bone (FDB). Methods SPECT and X-ray were performed in 35 cases of FDB proven pathologically during the period of 1999-2009. A retrospective study method was used to analyze the imaging results.Results Twenty-eight of 35 cases had lesions localized in only one bone (monostotic), 7 cases had them in many bones (polyostotic). Monostotic most occurred in bones of limbs, Polyostotic more involved in the unilateral limb. X-rays: Ground-glass-like changes in 22 cases,cystic swelling in 12 cases, loofah-like changes in one case. SPECT: Bone lesions showed localized increased radionuclide uptake. Conclusion Manifestations of FDB are various. The conventional imaging is lack of specific performance. The imaging examination should be referred each other and selected reasonably for diagnosis and differential diagnosis. Key words: Fibrous dysplasia of bone; Tomography, emission-computed, single-photon; Tomography, X-ray
