Frontal sinus mucocele: a rare complication of craniofacial fibrous dysplasia.

ABSTRACT

We present plain radiographic, computed tomographic and magnetic resonance imaging (MRI) findings in a 25-year-old female patient with craniofacial fibrous dysplasia (FD). Although FD has a tendency to involve craniofacial bones in a unilateral fashion, the involvement was bilateral and extensive in this case. An additional feature was the presence of a frontal sinus mucocele, presumably due to the involvement of the sinus recess by the dysplastic process. This complication of the craniofacial FD has been reported very infrequently in the literature.
