摘要目的 探讨脊柱骨纤维异常增殖症(FD)的CT和MRI特征.方法 回顾性分析19例经病理证实的脊柱FD患者的CT和MRI资料,其中19例均行CT检查(5例行增强扫描),11例行MR检查(6例行增强扫描).观察肿瘤在椎骨的位置、骨质破坏类型、病变边界、内部密度或信号、病变强化方式,及有无压缩骨折和脊柱畸形.结果 单发病变9例,脊柱多发病变10例.19例FD患者共有49个病灶,其中位于颈椎13个、胸椎23个、腰椎11个、骶骨2个.33个病灶椎体及附件均累及.CT扫描26个病灶为纯溶骨性骨质破坏,23个病灶基质内见斑片状磨玻璃样改变.44个病灶边界清晰,其中41个病灶周围有完整或部分硬化边包绕.32个呈不同程度膨胀性改变.28个病灶内部有残留骨嵴.19个出现椎体高度不同程度的减低.5例合并脊柱畸形.行CT增强扫描的5例患者共16个病灶,4个均匀明显强化,12个明显不均匀强化.行MR扫描的11例24个病灶中,14个病灶在T1WI上为等或低信号,10个为混杂信号.在T2WI上,6个为低信号,4个为高信号,14个为混杂信号.14个病灶周围可见薄层T1WI或T2WI低信号环包绕.行MR增强扫描的6例患者共15个病灶,7个均匀明显强化,8个不均匀明显强化.结论 脊柱FD的膨胀性溶骨性骨质破坏、磨玻璃样改变、周围硬化边以及增强扫描明显强化等特点有助于疾病的诊断. Objective To present the CT and MRI findings of the fibrous dysplasia(FD) of the spine.Methods CT and MRI findings were retrospectively evaluated in 19 cases of FD of spine,all of which were confirmed pathologically.Nineteen patients underwent CT plain scanning(19/19) and 5 had enhanced CT scanning(5/19).Patients were also examined by MRI plain scan(11/11) or MRI enhanced scan (6/11).The location of tumors,the type of bone destruction,the boundary of lesions,internal intensity or signal,the enhancement pattern of lesions,and presence of compression fractures,spinal deformity were observed.Result Nine cases had monostotic FD,while 10 had polyostotic FD.In all the 49 lesions of 19 cases,13 lesions were located in the cervical vertebrae,23 lesions in the thoracic vertebrae,11 lesions in lumbar vertebrae,and 2 lesions in sacral vertebrae.Thirty-three lesions involved both vertebral body and appendix.Pure osteolysis were found in 26 lesions on CT examinations.Peripheral osteosclerosis rims (41/49) and expansive lesions(32/49) were seen.Residual bone crest(28/49) and ground-glass opacity(23/49)were noted.Different degrees of vertebral compression were found in 19 lesions.Five patients had spinal deformity.On T1WI,14 lesions showed intermediate or low signal,and 10 lesions presented as heterogeneous signal.On T2WI,6 lesions had low signal intensity,4 lesions were noted as hyperintensive,and 14 lesions presented as heterogeneous signal.Multiple fluid-fluid levels were found in 1 lesion.Low signal rims were seen in 14 lesions.Twenty lesions of 11 patients had significant enhancement.Conclusion Expansive pattern,ground-glass opacity,peripheral osteosclerosis rims and significant enhancement were helpful findings for the diagnosis of spinal FD.
