The paranasal sinuses are a rare location of metastases. The most frequent infraclavicular primary tumor is the renal cell carcinoma (hypernephroma). We report a case of a 64-old-woman with a bilateral renal cell carcinoma and metastases in the paranasal sinuses with destruction of the skull base. If symptoms such as progressive indolent periorbital swelling or intermittent epistaxis occur in adults, one should consider a metastasis of a renal cell carcinoma to the paranasal sinuses even 10 years after nephrectomy.
鼻窦是转移瘤的罕见部位。锁骨下最常见的原发肿瘤是肾细胞癌（肾上腺样瘤）。我们报告一例64岁女性，患有双侧肾细胞癌并伴有鼻窦转移，累及颅底骨质破坏。如果成人出现如进行性无痛性眶周肿胀或间歇性鼻出血等症状，即使在肾切除术后10年，也应考虑肾细胞癌转移至鼻窦的可能性。
