Intraosseous Hemangioma of Frontal Bone: Report of Two Cases

ABSTRACT

Hemangioma arising in soft tissue is one of the most common tumors in the head and neck region. However, intraosseous hemangiomas are rare and account for only 0.5% to 1.0% of all osseous neoplasms. Most often, intraosseous hemangiomas are found in the vertebral column or calvarium. With regard to the facial skeleton, these lesions arise primarily in the mandible, maxilla, or nasal bones. For hemangiomas of the orbit or frontal bone, several cases have been reported. We present two cases of cavernous hemangioma arising from the superolateral orbital rim and frontal bone. In one case, the preoperative diagnosis with computed tomography(CT) scan was fibrous dysplasia. The diagnosis and treatment of this rare lesion are discussed.
