摘　　要：目的分析鞍区非肿瘤性病变的MRI影像特征,评价MRI对鞍区非肿瘤性病变的诊断价值。方法回顾性分析52例经手术病理及临床证实的鞍区非肿瘤性病变的MRI表现,其中空蝶鞍综合征10例,下丘脑错构瘤5例,Rathke裂囊肿10例,表皮样囊肿3例,皮样囊肿2例,动静脉畸形2例,海绵状血管瘤5例,蛛网膜囊肿2例,动脉瘤5例,朗格汉斯细胞性组织细胞增多症2例,淋巴细胞性垂体炎2例,鞍区增殖性炎症2例,垂体脓肿2例,全部病例均行MRI平扫及增强检查。结果鞍区不同类型的非肿瘤性病变有其不同的好发部位、好发年龄以及临床症状,MRI图像上也有各自的形态特征及信号特点。结论 MRI的多参数、多方位成像能够显示鞍区各种非肿瘤性病变的影像学特征,对鞍区非肿瘤性病变的诊断与鉴别诊断具有重要临床价值。Objective：To analyze the MRI features of sellar non- neoplastic lesions and to evaluate the MRI diagnosis value. Methods ： The MRI findings of 52 cases with sellar non - neoplastic lesions proved by operation and pathology were analyzed retrospectively. There were I0 cases of empty sella syndrome, 5 cases of hypothalamlc hamartoma, I0 eases of Rathke cleft cyst ,3 cases of epidermoid cyst ,2 cases of dermoid cysts ,2 cases of arterlovenous malformation ,5 eases of cav- ernous hemangioma, 2 eases of arachnoid cyst, 5 cases of aneurism, 2 cases of Langerhans cell histiocytosis, 2 cases of Lymphocytic hypophysitis, 2 eases of proliferative inflammation, 2 cases of abscess of pituitary, and all of the eases were performed conventional and enhanced MR/. Results： Different types of the sellar non - neoplastic lesions had their specific predilection sites, predilection ages and clinical symptoms ,and the MRI images had their respective morphologie and signal characteristics. Conclusion： Multiparameter and muhiaspeet images can show the different imaging features of various sellar non - neoplastic lesions, and MRI is of great value in diagnosis and differential diagnosis of sellar non - neoplastic lesions
