18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography (CT) has become the standard of care in staging, restaging, and response assessment of various malignancies including malignant melanoma. However, nonspecific uptake of FDG can occur in infectious and inflammatory conditions and can mimic a tumor. We present here a case of gossypiboma of the axillary region with FDG uptake detected in a patient with malignant melanoma of the upper extremity and discuss the potential pitfalls of this entity on FDG-PET/CT.
18F-氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）联合计算机断层扫描（CT）已成为包括恶性黑色素瘤在内的各种恶性肿瘤分期、再分期及疗效评估的标准诊疗方法。然而，FDG在感染和炎症性疾病中可出现非特异性摄取，可能会与肿瘤表现相似。我们在此报告1例上肢恶性黑色素瘤患者腋窝区域棉籽瘤伴FDG摄取的病例，并讨论该病变在FDG-PET/CT上可能存在的陷阱。
