title: Giant ossifying fibroma complicated by mucocele of sphenoid sinus--case report.
abstract: Ossifying fibroma is a benign tumour that rarely involves the skull. It is most commonly seen in the facial bones with a particular predilection for the mandible. It shares many pathological features with fibrous dysplasia. Ossifying fibroma is an expansive lesion and shows larger non-ossified areas of fibrous tissues. When the tumour is located deeply, encasing the optic-carotid complex, surgical removal becomes difficult because of its ossifying nature. Following surgical resection, the recurrence rate is very low. In the present study, a rare case of giant ossifying fibroma of sphenoid bone which had an intracranial extension with a coexistent mucocele is reported.
