动脉瘤样骨囊肿在全身骨显像及SPECT/CT断层融合显像上的影像学特征

Imaging features of aneurysmal bone cyst on whole-body bone imaging and SPECT/CT fusion imaging

目的探究动脉瘤样骨囊肿在全身骨显像及SPECT/CT断层融合显像中的影像特征,以提高动脉瘤样骨囊肿的诊断准确率。方法回顾性分析2016年1月~2022年5月在我院行全身骨显像及SPECT/CT断层融合显像并且术后病理诊断为动脉瘤样骨囊肿的患者,总结其在全身骨显像及SPECT/CT断层融合显像上的影像学特征。结果在我院行全身骨显像及断层融合显像且术后病理诊断为动脉瘤样骨囊肿的患者共24例,原发19例,继发5例,大多为青少年,病变主要分布于四肢长骨,也见于肋骨及骨盆骨,病变部位主要呈膨胀性骨质破坏伴相应部位骨代谢增高。结论全身骨显像联合SPECT/CT断层融合显像可较好地显示动脉瘤样骨囊肿的影像学特征及骨代谢情况,有助于动脉瘤样骨囊肿的定性诊断。

Objective To explore the imaging features of aneurysmal bone cyst in whole-body bone imaging and SPECT/CT tomosynthesis imaging,so as to improve the diagnostic accuracy of aneurysmal bone cyst.Methods A retrospective analysis was performed on patients who underwent whole-body bone imaging and SPECT/CT tomosynthesis imaging,pathologically diagnosed with aneurysmal bone cyst in our hospital from January 2016 to May 2022.We summarized its imaging features in whole-body bone imaging and SPECT/CT tomosynthesis imaging.Results Twenty-four patients underwent whole-body bone imaging and SPECT/CT tomosynthesis imaging in our hospital and were pathologically diagnosed as aneurysmal bone cysts,including 19 primary cases and 5 secondary cases,and mostly teenagers.It distributed in the long bones of the extremities,but also in the ribs and pelvic bones.The lesions were mainly expansile bone destruction with different degrees of increased bone metabolism in the corresponding parts.Conclusion Whole-body bone imaging combined with SPECT/CT tomosynthesis imaging can better display the imaging features and bone metabolism of aneurysmal bone cysts,which is helpful for the qualitative diagnosis of aneurysmal bone cysts.
