摘　　要：目的观察脊椎侵袭性血管瘤^(18)F-FDG PET/CT表现。方法回顾性收集24例脊椎侵袭性血管瘤患者,病变位于颈椎6例、胸椎14例、腰椎4例;观察其^(18)F-FDG PET/CT特点,比较具有不同CT表现病灶的最大标准摄取值(SUV_(max))。结果24例中,5例(5/24,20.83%)病变局限于椎体、19例(19/24,79.17%)病变累及椎体及附件;其中10例(10/24,41.67%)病变椎体见溶骨性破坏及内部残留骨质,6例(6/24,25.00%)伴单纯溶骨性破坏,4例(4/24,16.67%)伴骨小梁增粗、稀疏,4例(4/24,16.67%)骨质未见明显异常。相比邻近非病变椎体,12例(12/24,50.00%)病灶放射性摄取增高、9例(9/24,37.50%)接近、3例(3/24,12.50%)减低;14例(14/24,58.33%)放射性分布均匀、10例(10/24,41.67%)不均匀。24例血管瘤的SUV_(max)[2.50(1.53,4.13)]与肝脏SUV_(max)(2.79±0.53)差异无统计学意义(Z=0.261,P=0.794);其中,伴骨皮质破坏病灶的SUV_(max)高于无破坏病灶(P<0.05),伴骨折病灶的SUV_(max)高于无骨折病灶(P<0.05)。结论脊椎侵袭性血管瘤CT表现多样,其^(18)F-FDG代谢接近肝脏,合并骨皮质破坏及骨折病灶的代谢较高。Objective To observe^(18)F-FDG PET/CT manifestations of vertebral aggressive hemangioma.Methods Totally 24 patients with vertebral aggressive hemangioma were retrospectively enrolled,including 6 cases with lesions in cervical vertebrae,14 cases in thoracic vertebrae and 4 cases in lumbar vertebrae.^(18)F-FDG PET/CT characteristics of lesions were observed,and the maximum standard uptake value(SUV_(max))of lesions were compared among lesions with different CT performances.Results Among 24 cases,the lesion limited in vertebral body in 5 cases(5/24,20.83%)but affected vertebral body and appendages in 19 cases(19/24,79.17%).Accompanied vertebral osteolytic destruction and internal residual bone were noticed in 10 cases(10/24,41.67%),simple osteolytic destruction was found in 6 cases(6/24,25.00%),thickened and sparse trabeculae was observed in 4 cases(4/24,16.67%),while 4 cases(4/24,16.67%)without significant bone abnormalities.Compared to adjacent non diseased vertebrae,the radioactive uptake of lesions increased in 12 cases(12/24,50.00%),approached in 9 cases(9/24,37.50%)and decreased in 3 cases(3/24,12.50%).Uniform distribution of radioactivity was noticed in 14 cases(14/24,58.33%),while uneven distribution of radioactivity was found in 10 cases(10/24,41.67%).No significant difference of SUV_(max)was found between hemangioma lesions(2.50[1.53,4.13])and liver tissue(2.79±0.53)(Z=0.261,P=0.794).SUV_(max)of lesions with cortical bone destruction was higher than that of those without destruction(P<0.05),of those with fractures was higher than lesions without fractures(P<0.05).Conclusion Vertebral aggressive hemangioma had diverse CT manifestations,with^(18)F-FDG metabolism similar to liver.Vertebral aggressive hemangioma with cortical bone destruction and fractures had higher metabolism.
