摘要
目的探讨脊柱骨巨细胞瘤的CT及MRI表现。方法搜集经手术病理确诊的脊柱骨巨细胞瘤患者4例,男1例,女3例,年龄27～49岁,分析CT及MRI表现。结果发生于骶椎2例,胸椎1例,腰椎1例。CT表现为溶骨性膨胀性骨质破坏,并显示软组织肿块。MRI表现为病灶在T1WI为等或低信号,T2WI为混杂低～高信号。结论结合CT、MRI检查,可提高脊柱骨巨细胞瘤诊断的准确性。二者在肿瘤内部结构的显示、受累范围以及邻近组织的关系等方面能作出正确评价,可为临床治疗提供重要的影像资料。
Objective To explore CT and MRI features of the spinal giant cell tumors（GCT）.Methods CT and MRI manifestations in 4 cases（ 1 male and 3 females with ages raging from 30 to 49 years）of Spinal giant cell tumors by pathology were analyzed. Results 2 lesion localized in Sacrum, 1 in Thoracic, 1 in lumbar. The main CT signs were expanding bone destruction and soft tissue. MRI examination showed the intermediate to low signal on T1WI,and low to high-mix signal on T,WI. Conclusion Combined with CT and MRI examination can improve the accuracy of the spinal giant cell tumors（GCT）.CT and MRI can make the correct evaluation at the display of the interual structure,involvement of the scope and relationship to adjacent tissue,and provide important image information for clinical treatment.
