The increased use of cone-beam computed tomographic (CBCT) scans has made it increasingly necessary to evaluate incidental findings on CBCT scans. This report describes the case of a 66-year-old female patient who presented to the Department of Oral and Maxillofacial Pathology, Radiology and Medicine at the College of Dentistry of the author's institution and underwent a CBCT scan for maxillary alveolar process implant planning. Upon evaluation of the CBCT scan, a radiopaque (soft tissue attenuation) mass in the left superior aspect of the nasal cavity and left locule of the sphenoid sinus with opacification of the left locule of the sphenoid sinus was incidentally noted. These radiographic findings were suggestive of a space-occupying mass with a high possibility of malignancy. A further medical evaluation confirmed renal cell cancer metastasis to the sphenoid sinus. This study shows the significance of reviewing the entire CBCT scan for incidental findings.
锥形束计算机断层扫描（CBCT）的使用日益增加，使得评估CBCT扫描中的偶然发现变得越来越必要。本报告描述了一名66岁女性患者的病例，该患者到作者所在机构牙科学院的口腔颌面病理学、放射学和医学系就诊，并接受了CBCT扫描以进行上颌牙槽突种植体规划。在评估CBCT扫描时，偶然发现鼻腔左上方和蝶窦左房有一个不透射线（软组织衰减）肿块，蝶窦左房出现混浊。这些影像学表现提示存在占位性肿块，高度怀疑为恶性。进一步的医学评估证实为肾细胞癌转移至蝶窦。本研究表明了全面检查CBCT扫描以发现偶然发现的重要性。
