摘　　要：目的探讨脊柱孤立性浆细胞瘤(SBP)的18F-脱氧葡萄糖(FDG)正电子发射断层显像/X线计算机体层成像(PET/CT)诊断价值。方法收集3例经手术病理证实的SBP患者的PET/CT图像,结合文献对其临床、病理和影像学表现进行回顾性分析。结果 3例肿瘤均发生于胸椎,分别发生于T4、T6和T11,3例病变均位于椎体,PET/CT表现为椎体膨胀性、穿凿样溶骨性骨质破坏及软组织肿块,边缘有硬化带,呈中-高度不均匀葡萄糖代谢增高。结论脊柱孤立性浆细胞瘤好发于中老年,以胸椎为好发部位,PET/CT全身扫描有助于鉴别诊断,提高诊断的准确性。Objective To discuss the diagnostic value of lSF-fluorodeoxyglucose （lSF-FDG）PET/CT in solitary bone plasmacytoma （SBP）. Methods Three cases of SBP confirmed by surgery and pathology were retrospectively studied. And based on the clinical manifestation, pathological results and imaging findings, the related literatures with SBP were reviewed. Results Three cases had lesions in thoracic spine, respectively locating in T4, T6 and T11, le sion was found in all cases. The image features showed as expansive osteolytic or punched-out destruction of bone with clear border, and soft tissue mass, and the border hardened zone. Lesions in PET/CT showed the increase of glu cose metabolism. Conclusion SBP commonly occurs in the elderly and mainly locates at thoracic spine. PET/CT scanning is helpful in differential diagnosis and can improve the accuracy of the diagnosis.
