[Radiological findings in therapy planning and follow-up control of fibrous dysplasia]

25 patients with fibrous dysplasia have been treated surgically between 1980 and 1989. For monostotic manifestations which occurred mostly in the lower jaw, as well as for the follow up control, the conventional x-ray examination beneath anamnestic data was sufficient. Polyostotic extracranial lesions have mainly been diagnosed by scintigraphy. For exact statements about the extend and the involvement of functionally important structures, specially in the orbital and skull base region, CT proved to be the most effective diagnostic method by showing simultaneously bony and soft tissue structures. To our knowledge not yet described in the literature, we diagnosed a manifestation of several cervical vertebrae in one case.
