Abstract
|
|
|
Fibrous dysplasia is a benign bony disorder that contains trabeculae of poorly calcified primitive bone formed by osseous metaplasia. It is also characterized by replacement of normal spongiosa by abnormal fibrous tissues. We retrospectively
analyzed
the computed tomographic (CT) findings of 29 cases with clinically and radiologically diagnosed craniofacial fibrous dysplasia. In 2 cases, only cranial bones were involved and in 7 cases only facial bones were involved. Involvements of both
cranial and
facial bones were noted in the remained 20 cases. The commonly involved bones in the decreasing order of frequency were as follows: frontal, sphenoidal , ethmoidal and temporal bones in cranium and maxilla, zygoma, lacrimal bones and mandible in
facial
bones. Even though plain films are enough to diagnose the fibrous dysplasia, we think that CT is useful in more accurate diagnosis by demonstrating amorphous "ground-glass" appearance in the lesion and defining the exact extent of craniofacial
fibrous
dysplasia.
