Although hemangioma is a common soft tissue tumor in the oral and maxillofacial region, hemangioma of bone is very rare, especially in the maxilla. A 47-year-old woman was referred to our hospital because of a painless mass at the base of the right ala nasi. Panorama X-ray films showed a well-defined round radiopaque region, characterized by well-marked spoke-wheel trabeculation diverging from the center of the mass. Computed tomography (CT) revealed a mixed density mass at the base of the right ala nasi. The mass was characterized by a spoke-wheel or honeycomb pattern. We performed surgical excision, and fortunately there was no excessive hemorrhage during the operation. The lesion was diagnosed as a cavernous hemangioma with osteogenesis on pathological examination. The macroscopic and microscopic findings were characterized by a radial pattern of osteogenesis, consistent with the findings on X-ray film.
