Hump on head: Rare case of bi-frontal fibrous dysplasia.

Abstract

<h4>Background</h4>FD is relatively rare in the craniofacial region, accounting for only 20% of all cases. Currently, two general subtypes of FD are recognized: monostotic and polyostotic. The monostotic form is more frequent, accounting for 75% to 80% of fibrous dysplasia cases.<h4>Case description</h4>An 18-year-old male presented with the complaint of bony-hard swelling over the forehead for 8 years. Radiology showed an expansile osseous lesion involving frontal bones. The patient underwent bi-frontal craniectomy with gross total resection of tumour mass with titanium mesh cranioplasty. His postoperative period was uneventful and was discharged on the seventh postoperative day.<h4>Conclusion</h4>The cases of monostotic skull fibrous dysplasia should be treated by resection of the affected bone and cranioplasty. However, a more conservative re-contouring may be carried out in cases with multifocal involvement or when the excision is considered risky due to proximity to the major venous sinuses.
