Prätherapeutische Diagnostik der fibrösen Dysplasie

A safe differentiation of fibrodysplastic lesions from "real" bone tumours is of high importance because a fibrous dysplasia often requires no further therapy. While polyostotic involvement of fibrous dysplasia can be safely diagnosed before therapy, in monostotic disease differential diagnostic problems may occur. In the present investigation only in 6 of 14 mon- and biostotic lesions caused by fibrous dysplasia a correct diagnosis could be established by radiologic methods. However, in all cases of fibrous dysplasia malignancy could be excluded by radiology and the false diagnosis had no therapeutic consequences.
