| 目的 观察脊椎侵袭性血管瘤18F-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18F-FDG PET/CT特点,比较具有不同CT表现病灶的最大标准摄取值(SUVmax)。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SUVmax 与肝脏SUVmax(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SUVmax高于无破坏病灶(P＜0.05),伴骨折病灶的SUVmax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18F-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 18F-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. 18F-FDG PET/CT characteristics of lesions were observed, and the maximum standard uptake value (SUVmax) 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 SUVmax was found between hemangioma lesions (2.50) and liver tissue (2.79±0.53) (Z=0.261, P=0.794). SUVmax 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 18F-FDG metabolism similar to liver. Vertebral aggressive hemangioma with cortical bone destruction and fractures had higher metabolism. |
