We retrospectively identified eight patients who underwent F-18 FDG PET/CT and had diagnostic findings of postradiation pelvic insufficiency fracture. The fractures had a median SUV(max) of 2.5 (range, 1.6 to 6.0) and were initially interpreted as possible metastases in six patients. A new bone lesion developing in the sacrum, pubic ramus, or acetabulum after radiation for pelvic malignancy is likely to be a postradiation pelvic insufficiency fracture, even if associated with increased FDG uptake at PET.
我们回顾性地确定了 8 名接受 F-18 FDG PET/CT 检查且诊断为放射性骨盆失能性骨折的患者。这些骨折的 SUV(max)中位数为 2.5（范围，1.6 至 6.0），其中 6 名患者最初被解释为可能发生了转移。在骨盆恶性肿瘤放疗后，骶骨、耻骨支或髋臼出现新的骨病变，即使 PET 显示 FDG 摄取增加，也很可能是放射性骨盆失能性骨折。
