PURPOSE: To describe the clinical and radiologic features of 4 cases of ossifying fibroma affecting the orbit and to review the literature on orbital involvement by the tumor. METHODS: Small case series. RESULTS: Four patients (3 children and 1 adult) with ossifying fibromas invading the orbit were examined. Two of the 3 children were examined for ossifying fibromas on the orbital roof. One had the psammomatoid form of the disease and the other the trabecular variant. Despite striking differences in the histologic pattern and in the radiologic appearance of the lesions, both children displayed a significant degree of orbital inflammation mimicking orbital cellulitis. The third child and the adult patient had the orbit involved by trabecular ossifying fibromas invading the orbital floor. The tumor of the adult clearly originated in the maxilla, filled the maxillary sinus, and eroded the orbital floor. The tumor of the third child occupied the maxillary, ethmoid, and sphenoid sinuses. In both cases, the clinical presentation was painless eye dystopia and proptosis. CONCLUSIONS: Regardless of the histologic pattern (trabecular or psammomatoid), ossifying fibromas can induce a substantial degree of orbital inflammation in children and must be included in the differential diagnosis of acute orbital inflammation during childhood.
