title: [Bilateral maxillary sinus metastasis of renal cell carcinoma: a case report].
abstract: A 58-year-old man presented with lasting nasal obstruction. He had undergone right nephrectomy for renal cell carcinoma 11 years ago and right lobectomy for pulmonary metastasis 10 years ago. Paranasal sinus CT scans showed a soft tissue mass in the bilateral maxillary sinus. Abdominal CT showed left renal mass. Each mass was enhanced on the contrast-enhanced viewing. The paranasal mass biopsy was performed and resulted in profuse bleeding. Pathological examination was a metastasic renal cell carcinoma. After embolization of feeding artery, debulking surgery was performed. Postoperatively he was given radiotherapy and interferon therapy.
