Dual-time-point 18 F-flluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) can be used to differentiate benign vascular tumors from other malignant growths. We present the case of a 70-year-old woman with a history of cervical carcinoma who was referred for PET/CT to examine a left chest wall tumor noted on CT, which involved the adjacent rib and pleura, thus raising the suspicion of metastasis. The chest wall tumor demonstrated moderate FDG uptake and further decreased uptake at the delayed-phase scanning, corresponding to biodistribution of FDG in the blood pool. These findings indicated a benign hemangioma rather than a metastasis.
双时相 18 F-氟代脱氧葡萄糖（FDG）正电子发射断层扫描（PET）/计算机断层扫描（CT）可用于区分良性血管肿瘤和其他恶性肿瘤。我们报告了一例 70 岁女性患者的病例，该患者患有宫颈癌，因 CT 检查发现左胸壁肿瘤而接受 PET/CT 检查，该肿瘤累及相邻肋骨和胸膜，因此怀疑转移。胸壁肿瘤显示中等程度的 FDG 摄取，在延迟期扫描时摄取进一步减少，这与 FDG 在血池中分布的生物分布相一致。这些发现表明是良性血管瘤，而不是转移。
