摘要
目的:探讨脊柱原发性骨淋巴瘤(PBL)18F-FDG PET/CT影像表现,提高对本病的影像诊断水平.方法:回顾性分析我院经病理确诊的12例脊柱PBL的18F-FDG PET/CT影像表现,对肿瘤发生部位、骨质破坏类型、软组织肿块密度及侵犯范围、18F-FDG最大标准摄取值(SUVmax)进行分析.结果:(1)病变部位:1例累及颈椎,3例累及胸椎,4例累及腰椎,2例同时累及胸腰椎,2例累及骶椎.(2)骨质破坏类型:溶骨型骨质破坏9例,混合型骨质破坏3例.(3)软组织肿块:呈等或稍低密度,包绕椎体者11例,侵及椎管内者3例.(4)SUV-max:摄取范围为9.8-25.9(15.12±4.13).结论:脊柱PBL常表现为FDG代谢明显活跃,结合CT密度及形态特征能够提高该病的诊断.
Abstract
Objective:To investigate the 18F-FDG PET/CT imaging features of spinal primary bone lymphoma(PBL),and to improve the imaging diagnostic level of this disease.Methods:The 18F-FDG PET/CT images of 12 patients with spinal PBL diagnosed pathologically in our hospital were analyzed retrospectively.The tumor location,bone destruction type,soft tissue mass density and invasion range,and the maximum standard uptake value(SUVmax)of 18F-FDG were analyzed.Results:(1)Lesion location:1 case involved cervical vertebra,3 cases involved thoracic vertebra,4 cases involved lumbar vertebra,2 cases involved both thoracic and lumbar vertebra,and 2 cases involved sacral vertebra.(2)Type of bone destruction:9 cases of osteolytic bone destruction,3 cases of mixed bone destruction.(3)Soft tissue mass:it was isodense,wrapped around the vertebral body in 11 cases,and invaded into the vertebral canal in 3 cases.(4)SUVmax:the intake range is 9.8-25.9(15.12±4.13).Conclusion:Spinal PBL often shows active FDG metabolism,and combining with CT density and morphological features can improve the diagnosis of the disease.
