Radiation-related sarcoma is a rare but serious complication for patients after receiving radiation therapy initially for their primary malignancy. However, it usually takes several years and needs enough in-field radiation dose to develop this sarcoma. We describe a 60-year-old man with right axillary sarcoma revealed by whole-body F-FDG PET/CT 1 year after chemoradiotherapy, which presented ultrashort latency period and did not match the consensus definition of radiation-related sarcoma. Besides, metastatic sarcoma to small intestine was accidentally noted in the F-FDG PET/CT image.
放射性肉瘤是患者在最初接受原发恶性肿瘤放射治疗后发生的一种罕见但严重的并发症。然而，通常需要数年时间并且需要足够的照射野内放射剂量才能发展为这种肉瘤。我们描述了一名 60 岁男性，在接受化疗和放疗后 1 年全身 F-FDG PET/CT 检查发现右侧腋窝肉瘤，其潜伏期非常短，不符合放射性肉瘤的共识定义。此外，在 F-FDG PET/CT 图像中还意外发现了小肠转移肉瘤。
