摘要
目的：通过对骶骨肿瘤MRI表现的分析，探讨其对骶骨肿瘤的诊断价值。方法：回顾性分析经手术病理证实的14例骶骨肿瘤的MRI影像特征，所有病例均摄X线平片检查；14例骶骨肿瘤中脊索瘤5例，骨巨细胞瘤3例，转移瘤2例，神经鞘瘤2例，软骨肉瘤1例，畸胎瘤1例，部分行CT检查。结果：各种骶骨肿瘤的MRI征象包括病变不同的范围及中心位置，MRI信号强度，骶骨的骨质破坏，骶孔扩大变形，软组织肿块，病灶内钙化及骨嵴形成，髓腔浸润。结论：MRI可作为骶骨肿瘤有效的术前诊断方法，对临床指导治疗有重要意义。
Abstract
Objective: To explore the value of MRI in the diagnosis of sacral tumors. Methods: MRI appearances of 14 cases of sacral tumors proved by histopathological evaluation were retrospectively analysed. There were 5 cases of chordomas, 3 cases of giant cell tumors, 2 cases of metastatic tumors, 2 cases of neurogenic tumors, 1 case of chondrosarcoma and 1 case of teratoma. All cases were studied with X-ray plain films and MRI, some with CT. Results: characteristic MRI signs of all kinds of sacral tumors included different lesion extent and location, MRI signal intensity, sacrum destruction, sacral canal and sacral foramen deformation, soft tissue mass, calcification and remaining bone crista, bone marrow infiltration． Conclusion: MRI is effective in the preoperative diagnosis of sacral tumor and is of clinical significance to the treatment of sacral tumor.
