The case concerns 28-year-old patient, presented with gradual painless prominence of the right eye noted for 02 years. The ophthalmological examination of the right eye found a decreased visual acuity, non-axial proptosis, limited ocular motility examination and stage 1 papilledema on fundoscopy. CT scan showed an enhanced extra-conal mass of the right orbit with compression of the right optic nerve was noted. An excisional biopsy was done and histopathological examination confirmed a ossifying fibroma. Discussion: Ossifying fibroma is a benign fibro-osseous lesion rarly located in orbital cavity. Clinical presentation and complications vary according to its location. Imaging, based in CT scan and MRI, shows clearly demarcated, round or ovoid lesions with osteoblastic and lytic areas in the central matrix, and concentrically expanding solitary mass with a thin sclerotic margin. Conclusion: Ossifying fibroma is a rare bony neoplasm of orbit which needs multidisciplinary approach to be differentiated from other orbital tumors. Radiological and histopathological correlation are mandatory for an appropriate diagnosis to ensure complete excision to prevent recurrences.
