Giant cell reparative granuloma of the craniofacial complex: case report and review of the literature.

Giant cell reparative granuloma (GCRG) is an infrequent non-tumoural lesion affecting particularly the maxillary and mandibular bones and only rarely the cranial bones. The pathogenesis is still controversial and the differential diagnosis, especially from giant cell tumours of bone, is difficult. A case of GCRG of the sphenoid masquerading as an intracranial tumour is reported here. The relevant literature is reviewed.
