摘要
目的分析椎体原发性肿瘤的MRI表现,探讨其诊断及鉴别诊断。方法回顾性分析经临床穿刺活检或手术病理证实的脊柱原发性肿瘤33例。分别观察椎体、附件及椎间盘的病变情况,椎体破坏程度及周围软组织MRI表现。结果脊索瘤表现为溶骨性破坏,伴有软组织肿块。巨细胞瘤呈膨胀性生长,其余各种肿瘤各有其MRI表现。结论MRI在明确病灶部位和范围及定性方面具有很大的价值。
Objective:To analyse the features of primary tumours in spine.Methods:33 patients with primary tumours in spine proved by pathology were reviewed, and observe MRI features of spine, spinal accessory, intervertebral discs, and soft tissure around destroyed spine were observed.Results:Osteolytic lesions with soft tissue mass were seen in chordoma. Giant cell tumor showed typical expansive growth and each of the other tumors showed its typical MRI appearance.Conclusion:MRI can provide more information about the exact site of origin, extent and nature.
