目的观察并探讨鞍区肿瘤MRI影像学特征、临床价值及鉴别诊断要点。方法选取我院2006年3月至2011年4月收治经外科手术或病理检查确诊为鞍区肿瘤患者102例MRI影像学资料,归纳总结不同鞍区肿瘤类型MRI影像学特征,寻找鉴别诊断关键。结果本组102例患者中经外科手术或病理检查确诊垂体腺瘤30例,三叉神经瘤15例,脑膜瘤22例,颅咽管瘤12例,胶质瘤10例,生殖细胞瘤7例,脊索瘤2例,畸胎瘤2例,表皮样囊肿1例,蛛网膜囊肿1例;MRI诊断与外科手术或病理检查确诊符合率为96.1%(98/102)。不同类型鞍区肿瘤具有不同好发年龄、部位、影像学表现特点等。结论 MRI诊断鞍区肿瘤临床确诊符合率高,能够清晰显示肿瘤区域及周围毗邻影像学特征,可广泛用于鞍区肿瘤临床诊断中。
Objective To observe and discuss the MRI features, clinical value and differential diagnosis of sellar tumors. Methods From March 2006 to April 2011 in our hospital, 102 patients with metastatic tumors diagnosed by surgery or pathology were selected for MRI imaging. The imaging features of different types of tumors in the sellar region were summarized, and the key to differential diagnosis was found out. Results Totally 102 cases of pituitary adenoma, 15 cases of trigeminal neuroma, 22 cases of meningioma, 12 cases of craniopharyngioma, 10 cases of glioma, 7 cases of germ cell tumor were diagnosed by surgery or pathological examination. 2 cases of chordoma, 2 cases of teratoma, 1 case of epidermoid cyst and 1 case of arachnoid cyst. The coincidence rate of MRI diagnosis and surgical operation or pathological examination was 96.1% (98/102). Different types of sellar tumors have different hair age, location, imaging features and so on. Conclusion MRI diagnosis of sellar tumors in clinical diagnosis of high coincidence rate, can clearly show the adjacent tumor imaging and imaging features, can be widely used in the clinical diagnosis of sella tumors.
