      【摘要】 目的 分析脊柱孤立性浆细胞瘤的 18F-FDG PET/CT影像表现，以提高其诊断水平。方法 回顾性分析2011年1月至2016年3月间我院收治的15例经临床病理证实的脊柱孤立性浆细胞瘤的PET/CT征象。结果 15例脊柱孤立性浆细胞瘤均只累及单个椎体，8例位于胸椎，6例位于颈椎，1例腰椎。表现为椎体溶骨性骨质破坏，边缘清晰硬化，椎旁软组织肿块，无骨膜反应，可见粗大的骨嵴，中-高 18F-FDG摄取。结论 PET能提示脊柱孤立性浆细胞瘤的恶性生物学行为，明确诊断还需要结合临床、同机CT和病理学检查。

【Abstract】 Objective To analyze the 18F-fluorodexoxyglucose (18F-FDG) positron emission tomography-com-puted tomography (PET/CT) findings of solitary plasmacytoma in spine, and to improve its recognition and diagnosticaccuracy. Methods The 18F-FDG PET/CT features of 15 patients with solitary plasmacytoma in spine confirmed bysurgery and (or) excisional histopathology in our hospital from Jan. 2011 to Mar. 2016 were retrospectively analyzed.Results In each of the 15 cases, the tumor was found located in a single type of vertebra, including 6 cases in cervi-cal vertebra, 8 cases in thoracic vertebra, 1 case in lumbar. 18F-FDG PET/CT features included solitary lytic bone destruc-tion with well-defined margin, paraspinal soft tissue mass, large bone crest, no periosteal reaction, and moderate-high18F-FDG uptake. Conclusion PET can indicate malignant biological behavior of solitary plasmacytoma in spine, andclinical diagnosis, syn-modality CT and pathologic examinations are still needed to improve the diagnostic accuracy ofthe disease.
