Nasosinus metastases from kidney cancer are an unusual clinical presentation although some cases are reported in the literature. Among these cases, sphenoidal metastases are even rarer. Here we report a case of lone sphenoid metastasis in patients with papillary renal cell cancer. Eight months after radical nephrectomy, the patient presented with progressively worsening diplopia. Magnetic resonance imaging showed a mass in the right sphenoid sinus. Histopathological examination of the biopsy sample confirmed diagnosis of sinonasal metastasis from papillary renal cell carcinoma. The patient was declined for surgical management and received stereotactic body radiation therapy. Reassessment MRI at 4 months showed a complete response of the treated sphenoid lesion.
尽管文献中有一些肾癌鼻窦转移的病例报道，但这种临床表现并不常见。在这些病例中，蝶窦转移更为罕见。在此，我们报告一例乳头状肾细胞癌患者孤立性蝶窦转移的病例。根治性肾切除术后8个月，患者出现复视进行性加重。磁共振成像显示右侧蝶窦有一肿块。活检样本的组织病理学检查证实为乳头状肾细胞癌鼻窦转移。该患者拒绝手术治疗，接受了立体定向体部放射治疗。4个月后的重新评估磁共振成像显示，治疗后的蝶窦病变完全缓解。
