摘　　要：目的:探讨MRI在鞍区肿瘤诊断中的价值。方法:40例经手术和病理证实的鞍区肿瘤病人,对其MRI表现进行回顾性分析。结果:垂体瘤20例,颅咽管瘤8例,脑膜瘤6例,MRI表现具有特征性,术前诊断正确率较高。脊索瘤2例,星形细胞瘤1例,生殖细胞瘤1例,嗅神经母细胞瘤和浆细胞瘤各1例,MRI表现缺乏典型征象,往往难以诊断,其中3例误诊。结论:MRI检查,尤其是三维成像技术(横轴位、矢状位、冠状位)可显示鞍区肿瘤的内部结构、生长方式、侵犯范围及其与周围血管的关系,对鞍区肿瘤定位、定性诊断有重要价值。To explore the value of magnetic resonance imag-ing（MRI） in confirming the patients with tumors in sellar and parasellar area. Methods： MRI signs of 40 patients by surgically and pathologi-cally confirmed sellar and parasellar area tumors were analyzed retrospec-tively. Results ： Pituitary adenomas（ n = 20）, craniopharyngiomas（ n = 8） and meningiomas（ n = 6）had characteristic signs and most of them were confirmed by MRI. But chordoma（ n = 2）, astrocytoma（ n = 1 ）, germinoma （ n = 1 ）, esthesioneuroblastoma （ n = 1 ） and plasma-cell myeloma（ n = 1 ） were solidary lesions in sellar and parasellar area with-out any diagnostic signs and 3 cases were misdiagnosed. Conclusion ： MRI ,three dimensional images（axial, sagittal and coronal）in particular, can demonstrate inner characteristic, growth manner, infiltrating extend of tumors and the relationship between tumor and peri-tumor vessels. MRI has great value in the diagnosis of the sellar and parasellar neo-plasms.
