摘要:
目的 分析脊柱骨巨细胞瘤的影像学表现及进行临床相关性研究, 提高对该病的诊断及临床治疗。 方法 回顾性分析11例经病理证实的脊柱骨巨细胞瘤的影像学资料。 结果 11例肿瘤中位于颈椎2例, 胸椎4例, 腰椎2例, 骶椎3例。术后复发3例, 伴动脉瘤样骨囊肿3例。X线及CT表现为偏心性溶骨性破坏, 病灶内密度较均匀, 8例伴发病理骨折, 3例复发病例的影像学表现为虫蚀状溶骨性破坏, 边界不清。MR表现为T1WI呈等低信号, T2WI上表现为混杂高信号, 3例伴动脉瘤样骨囊肿的表现为多囊状高信号。 结论 脊柱骨巨细胞瘤影像学表现有一定的特征性, 对诊断、治疗及术后处理有重要价值。 Abstract:Objective This study aimed to analyze imaging findings of giant cell tumor of the spine and its clinical correlational study. Methods We retrospectively analyzed the imaging features of 11 cases giant cell tumor of the spine confirmed by pathology. Results In the 11 cases, 2 were located in the cervical vertebra, 4 in the thoracic vertebra, 2 in the lumbar vertebra, 3 in the sacral vertebra.Three of the postoperative cases were recurrence and three had aneurysm bone cyst.On X-ray and computed tomography images, the tumors showed expanding bone destruction and uniform density in lesion.Pathological fracture occurred in eight cases.Imaging findings of three recurrence cases showed moth-eaten osseous destruction and unclear boundary.Magnetic resonance images displayed homogeneous intermediate signal on T1WI and miscellaneous high signal on T2WI.Three cases with aneurysm bone cyst exhibited high signal of multiple cystic. Conclusion Giant cell tumor of the spine exhibited some characteristic features of imaging.Therefore, making a correct diagnosis and administering appropriate treatments and postoperative processing procedures are necessary. -

Figure 1. Post-operative recurrence of giant cell tumor of the fourth lum-bar vertebral body
A: MPR reconstruction showed that the fourth lumbar vertebral body andattachment structure exhibited osseous destruction.The fourth lumbar ver-tebral body was flattened and the boundary of destructive area was notclear; B: CTA showed that the tumor blood supply was rich.The tumorblood supply artery was also observed

Figure 2. Giant cell tumor of the eleventh thoracic vertebral body with an-eurysms bone cyst and pathologic fracture
A: MR images showed that the eleventh thoracic vertebral body was flattenedsimilar to a"dumbbell", and respectively showed low signal on T1WI andmixed high signal on T2WI.B: Soft tissue masses were observed on thevertebral side.Compression of the spinal cord was also observed
