Abstract

Primary sinonasal melanoma is a rare disease. We present a case of melanoma in sinuses without abnormal F-FDG activity anywhere in the scanned portion of the body. In further assessment, C-choline PET/CT revealed high activity in the paranasal sinuses, skull base, and adjacent brain, in agreement with the high signal on contrast-enhanced T1-weighted MRI scan, which suggested the residual tumor.

摘要

原发性鼻腔鼻窦黑色素瘤较为罕见。我们报告了一例鼻腔鼻窦黑色素瘤患者，全身扫描未见 F-FDG 摄取异常。进一步行 C-胆碱 PET/CT 检查发现副鼻窦、颅底和邻近脑区高摄取，与增强 T1WI 高信号一致，提示肿瘤残留。
