A 37-year-old man with multiple myeloma in remission underwent routine fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) study for disease restaging. Both FDG-PET and CT images showed focal abnormalities in the region of the T6 vertebra, but the fused images that are routinely provided with PET/CT could precisely localize the FDG active lesion to a soft tissue focus in the epidural space, away from a lytic nonactive vertebral body lesion despite their close proximity. The PET/CT scan identified a few other metabolically active osseous lesions out of many lytic bony changes throughout the skeleton. Accordingly, the patient received the correct management for an impending spinal cord compression at the appropriate time, in addition to systemic therapy for disease relapse.
一名处于缓解期的37岁多发性骨髓瘤男性患者接受了用于疾病再分期的常规氟脱氧葡萄糖-正电子发射断层扫描/计算机断层扫描（FDG-PET/CT）检查。FDG-PET和CT图像均显示T6椎体区域有局灶性异常，但PET/CT常规提供的融合图像能够将FDG活性病变精确地定位到硬膜外间隙的一个软组织病灶，该病灶与一个溶骨性无活性椎体病变虽位置紧邻，但相互分离。PET/CT扫描在全身多处溶骨性骨改变中发现了其他一些代谢活跃的骨病变。因此，除了针对疾病复发的全身治疗外，患者还在适当的时候接受了针对即将发生的脊髓压迫的正确治疗。
