摘要
目的 :通过对骶骨肿瘤CT及MR表现的分析 ,提高对其影像诊断的认识。材料和方法 :28例骶骨肿瘤 ,其中脊索瘤10例 ;神经源性肿瘤8例 ;转移瘤4例 ;巨细胞瘤5例 ;淋巴瘤1例。全部病例均行CT检查 ,22例行MR检查 ,并对其CT、MR表现进行分析。结果 :各种骶骨源性肿瘤及肿瘤样病变的征象包括 :软组织肿块 ,骶孔扩大变形 ,病灶内钙化及骨嵴形成 ,髓腔浸润 ,病变不同的中心位置及范围。脊索瘤、巨细胞瘤、神经源性肿瘤的MR信号有一定特点。结论 :CT特别是MR可作为骶骨肿瘤的有效诊断方法。
Purpose:To evaluate the value of CT and MRI in diagnosing skeletal tumors of sacrum.Materials and methods:28 cases with sacral tumor were analyzed.All cases were studied with CT and 22 cases of them with MR at the same time.Results:Soft tissue mass,sacral foramen obstruction,calcification and bone marrow involvement were fomed different ranges and location and characteristic MRI signal intensity.Conclusion:CT and MRI,as auxiliary methods,are effective in the diagnosis of tumors in sacrum.Diagnostic accuracy of the lesions could be improved by close combination with plain film,CT and MRI.
