Abstract:
Objective To study the imaging diagnostic methods of fibrous dysplasia.Methods 31 patients with fibrous dysplasia proved pathologically were studied. In addition to CT scan in 11 cases and MRI in 6 cases,plain films were performed in all 31 cases. The compartive analysis was made between the features of plain film and CT.Results Of 31cases, 18 patients had monostotic fibrous dysplasia and 13 polyostotic lesions. Roentgenologically, they were divisible into 4 type: cystic type(18 lesions),diffuse type(30 lesions),sponge groud-flesh type(2 lesions) and moth-eaten type(2 lesions). CT features of lesions were classified into 2 type: cystic expanded type(38 lesions) and osteosclerotic type(7 lesions).Conclusion X-ray film should be used as the first choice in diagnosis of fibrous dysplasia. CT is hightly sensitive in displaying the craniofacial lesions.The lesions can be correctly diagnosed in most instances,if plain film combined with CT.
