【摘要】 目的　探讨骶椎肿瘤的CT表现及其临床意义。方法　回顾性分析行CT检查并经临床病理证实的 14例 (男 9例 ,女 5例 )骶骨肿瘤 ,就骨质破坏 ,钙化 ,软组织肿块和病变与邻近组织的关系等方面进行分析。结果　转移瘤CT表现为椎体和附件骨质破坏 ,无钙化。脊索瘤亦表现为溶骨性骨质破坏 ,伴有软组织肿块 ,常有钙化。巨细胞瘤呈膨胀性生长 ,压迫周围组织或器官。神经纤维瘤、骨软骨瘤及软骨肉瘤的CT表现典型。结论　CT扫描在骶椎肿瘤的发现和估价病变方面具有较高的敏感性 ,对治疗计划的制订有重要的参考作用。更多还原

【Abstract】 Objective To evaluate the CT findings and clinical application in sacrum neoplasms.Methods Fourteen cases(9 male and 6 female)with sacrum neoplasms clinically or pathologically proved were restrospectively analysed.In these patients,CT scan were presented.The following aspects were evaluated:destruction of bone,calcification,soft tissue mass and the relationship between the lesions and their nearby structure.Results On CT scans in metastatic tumors,bony destuction in vertebral body and adnexa could be showed and there were no calcification.Osteolytic lesions with soft tissue mass and calcification were seen in chordoma.Giant cell tumor showed typical expansive growth and the structnres around tumors compressed.Neurofibroma,chondrosarcoa and osteochondroma had typical CT appearence.Conclusion CT scan in detection and evaluation of sacral neoplasms is more sensitive than X-ray plain film and is very helpful in guiding treatment planning.更多还原
