Management of paranasal sinus metastasis by percutaneous CT-guided permanent seed brachytherapy

Abstract Introduction A painful maxillary sinus metastasis in previously irradiated tissue required palliation. Methods and materials Lesion was treated by computed tomography–guided palladium103 implantation as an outpatient procedure; the lesion and its attendant facial pain and swelling resolved completely. Conclusion Computed tomography–guided permanent seed brachytherapy is a novel, rapid, effective, and low resource cost method of treating paranasal malignancy.
