Fibrous dysplasia of bone

The radiological features of 55 histologically confirmed and fully documented cases of fibrous dysplasia have been reviewed, together with a brief review of the method of presentation. There were 46 cases of monostotic fibrous dysplasia and nine polyostotic cases. The features of the two groups have been assessed separately, then compared. The possibility of more than one disease process having previously been included under the term fibrous dysplasia because of similar histology is discussed.
