The value of bone scintigraphy in diagnosis of fibrous dysplasia of bone

Objective To analyze the characteristics of bone scintigraphy in patients with fibrous dysplasia of bone （ FD）, and compare the images of primary bone malignancy and bone metastases and Paget＇s disease with the tindings of fibrous dysplasia of bone. Methods Twenty seven cases of FD which confirms by the surgery pathology were collected and analyzed retrospectively in the Sixth People＇s Hospital, Shanghai Jiaotong University from 2003 to 2007. All patients were routinely performed scanning with ^99Tcm-MDP bone scintigraphy in addition to conventional radiography. Results In 27 patients, 10 were male, and 17 were female. The onset mean age was （23. 15 ± 18.01 ） years （ ranging from 9 to 75） and under the age of 31 accounted for 55.56 %. X-ray performance mainly for ＂ground-glass＂ pattern, cystic type or sponge ground-flesh type. For bone scintigraphy, FD appears as an area of intensely increased uptake. Typical imaging characteristics including linear accumulation of radioactivity, normal bone scale and hemibody uptake. Conclusion Most of FD have the typical imaging appearances, bone scintigraphic play an important role in the diagnosis and differential diagnosis of FD.
