Abstract
Intraosseous hemangiomas are rare, comprising only 0.5% to 1% of all osseous neoplasms. The most common locations are the vertebral column and the skull bones; nevertheless, the maxillary bone is quite a rare location and only a few cases have been described in the literature thus far. We describe a case of a 48-year-old woman who was referred to our hospital with a suspected maxillary tumor incidentally discovered on (18) F-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging performed during a general medical examination. Computed tomography (CT) demonstrated a 3 cm bony tumor with a honeycomb appearance occupying the left maxillary sinus. Complete surgical resection via the Caldwell-Luc procedure was performed for the purpose of diagnosis and treatment. Histological examination revealed that the tumor was an intraosseous cavernous hemangioma originating from the maxillary bone. Although preoperative angiography and embolization were not performed, intraoperative-blood loss was minimal. No recurrence has been seen in a follow-up period of 3 years.
