Primary intraosseous hemangioma, though rarely affect the bones of the orbit, should be considered in the differential diagnosis when a patient presents an enlarging mass fixed to the bone in the orbit or signs of progressive painless proptosis. Assessing the exact site and extent of the hemangioma by means of a CT scan and MRI and establishing the vascular origin of the lesion, is critical in the therapeutical planning, since an inadequate management may result in a severe hemorrhage. Progressive proptosis and contour deformity require surgical treatment. Two cases of patients with primary intraosseus hemangioma of the supra-lateral orbital rim are reported. A bony healthy margin excision was performed, followed by immediate reconstruction of the orbit with calvarial bone grafts fixed with resorbable plates. After three-year follow-up there have not been evidence of local recurrence, and the functional and aesthetic results obtained have been very satisfactory.
