摘　　要：目的探讨斜坡肿瘤及肿瘤样病变的CT和MRI表现,以提高对该类疾病的认识及诊断的准确率。方法选取27例经病理证实为斜坡肿瘤及肿瘤样病变的术前CT和MRI检查资料,并对其进行回顾性分析,分析病变部位、形态、大小、CT及MRI特征及强化特点等。结果27例中原发性肿瘤15例,包括脊索瘤8例,软骨肉瘤3例,淋巴瘤1例,骨纤维结构不良1例,骨巨细胞瘤1例,骨软骨瘤1例;继发性肿瘤12例,包括鼻咽癌5例,侵袭性垂体腺瘤3例,脑膜瘤4例。结论CT检查对肿瘤钙化及骨质破坏的显示明显优于MRI检查,而MRI检查对肿瘤的大小、形态及侵及范围显示的更好,两者结合有利于提高肿瘤的诊断准确率。Objective To evaluate CT and MRI features in the clivus tumors and tumors-like lesions so as to improve the diagnosis and understanding of the disease.Methods The CT and MRI data of 27cases of the clivus tumors and tumors-like lesions confirmed by pathology were retrospectively analyzed,including the location,shape,size,CT and MRI features,the method and degree of enhancement.Results Among the 27 tumors,15 were primary tumors,including 8 chordomas,3 chondrosarcomas,1 lymphoma,1 fibrous dysplasia of bone,1 giant cell tumor,and 1 osteochondroma.12 were secondary tumors,including 5 nasopharyngeal carcinomas,3 invasive pituitary adenomas and 4 meningiomas.Conclusion CT is significantly superior to MRI in displaying calcification and bone destruction,while MRI can well demonstrate the size,shape and extension of the tumor,and the combination of CT and MRI is conducive to improving the diagnosis of the tumor.
