Fibrous dysplasia of the facial skeleton commonly involves the maxilla. It commonly involves one maxilla. CT scan shows a lesion that is confined to the bone with no soft tissue component. It is helpful in distinguishing fibrous dysplasia from a malignancy. Features of malignancy include osteolysis, destruction of sclerotic margins, and cortical destruction with soft tissue extension. The bony lesion shows a homogenous matrix with obliteration of maxillary sinus cavity.
