Abstract
An 81-year-old woman was admitted to our hospital because of right maxillary swelling, pain and nasal obstruction. The medial wall of the right maxillary sinus protruded to the nasal septum. Plain X-ray films showed destruction of the lateral bony wall, and plain CT scans showed destruction of the posterior bony wall of the right maxillary sinus. The tumor was invading the parapharyngeal space. These findings suggested a malignant tumor of the right maxillary sinus.
When needle biopsy was attempted intranasally, the needle could be inserted into the right maxillary sinus without any resistance. The pathological report was no malignancy, only coagulation.
The right cheeck and gingiva showed swelling abruptly. Emergency CT showed an osteolytic lesion of the alveolar bone. Right maxillary sinectomy was done. The pathological report was fibrosis, hyalinization and capillary dilatation, these finding are compatible with hemangioma of the right maxillary sinus. The authors review the Japanese literature and discuss the ethiology of hemangiomas of the nose and paranasal sinuses.
