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.
