摘要

18F-FDG在骨中的局灶性摄取一直令人担忧，特别是在有癌症病史的患者中。我们报告一例增加高代谢活动的上颌骨病变患者与多发性骨髓瘤的历史，是管理与明确的治疗。目标CT扫描显示异常的18F-FDG摄取为纤维发育不良。对于有癌症病史的患者，需要对PET/CT的局灶性骨活动进行警惕的解释，以避免假阳性读数。

Fibrous Dysplasia of Frontal Process of Maxilla: False-Positive Finding on ¹⁸F-FDG PET in Multiple Myeloma.

¹⁸F-FDG focal uptake in bone is always concerning, especially in patients with a history of cancer. We report a case of increasing hypermetabolic activity of a maxillary bone lesion in a patient with a history of multiple myeloma that was managed with definitive treatment. A targeted CT scan revealed that the abnormal ¹⁸F-FDG uptake was fibrous dysplasia. Vigilant interpretation is required for focal osseous activity on PET/CT in patients with a history of cancer to avoid false-positive readings.
