目的 :探讨脊髓内原发肿瘤的影像学特点。方法 :回顾总结 2 7例经手术及病理证实的脊髓内肿瘤的椎管造影、CTM及MRI特征 ,其中室管膜瘤 13例 ,星形细胞瘤 8例 ,脂肪瘤 3例 ,血管母细胞瘤 3例。结果 :椎管造影及CTM可显示肿瘤所在部位脊髓梭形膨大 ;MRI表现因肿瘤性质不同而异 ,可较准确显示其临床病理特征及与脊髓界限。结论 :椎管造影、CTM、MRI对脊髓内肿瘤定位诊断均有重要价值 ,其中MRI定性诊断及与肿瘤界限判定对手术有一定指导作用。
Objective: To investigate the imaging features of primary spinal cord tumors. Methods: The spinal canal imaging, CTM and MRI features of 27 intraspinal spinal cord tumors confirmed by operation and pathology were retrospectively reviewed. Among them, 13 cases of ependymoma, 8 cases of astrocytoma, 3 cases of lipoma and 9 cases of hemangioblastoma 3 cases. Results: Spinal angiography and CTM showed that the spondylolisthesis of the tumor site was swollen. The manifestations of MRI varied with the nature of the tumor, which could show the clinicopathological features and spinal cord boundaries more accurately. Conclusion: Spinal angiography, CTM and MRI have important value in the diagnosis of intraspinal spinal cord tumors, of which the qualitative diagnosis of MRI and the judgment of tumor boundary have some guidance on the operation.
