鞍区肿瘤性病变MRI诊断

Saddle area tumorous pathological change MRI diagnosis

目的：探讨鞍区肿瘤性病变的MR表现,提高MR对鞍区肿瘤性病变的诊断水平.方法：回顾分析38例经手术病理证实的鞍区肿瘤性病变,分析其MR信号特征、增强扫描强化特征以及与周围结构关系.结果：38例鞍区肿瘤性病变垂体腺瘤30例,脑膜瘤3例,颅咽管瘤2例,生殖细胞瘤1例,转移瘤1例,脊索瘤1例,根据病变部位、信号特征及强化特征,大部分病例可以做出正确的诊断.结论：MRI是评价鞍区肿瘤性病变的首选影像学检查技术,认真分析其MRI表现,对临床诊断及鉴别诊断具有重大意义.

The discussion saddle area tumorous pathological change MR pertormance,enhances MR to the saddle area tumorous pathological change diagnosis level. Methods：The review analyzes 38 examples after the surgery pathology confirmation saddle area tumorous pathological change,analyzes its MR signal characteristic,the enhancement scanning strengthening characteristic as well as with the periphery structure relations. Results：38 example saddle area tumorous pathological change pituitary gland adenoma 30 examples, the meningioma 3 examples, the craniopharyngioma 2 examples, reproduce the cytoma 1 example, the shift lump 1 example, the chordoma 1 example,according to the pathological change spot,the signal characteristic and the strengthened characteristic,the majority of case of illness may make the correct diagnosis. Conclusion： MRI is appraises the saddle area tumorous pathological change the first choice phantom study inspection technology, analyzes its MRI performance earnestly, has the great significance to the clinical diagnosis and the distinction diagnosis.
