目的探讨MRI应用于鞍上肿瘤的诊断价值。方法回顾性分析2009年5月—2012年9月间经手术或病理证实为鞍上肿瘤患者43例的临床资料,分析MRI检测的准确性。结果垂体腺瘤18例,颅咽管瘤10例,脑膜瘤9例,表皮样囊肿4例,生殖细胞瘤2例,各类肿瘤均有其特定的MRI影像特点。结论 MRI能正确显示鞍上肿瘤及其毗邻解剖结构,对不同的鞍上肿瘤信号特点可以较好区别,对肿瘤诊断有很大帮助。
Objective To investigate the diagnostic value of MRI in suprasellar tumors. Methods The clinical data of 43 patients with suprasellar tumors confirmed by surgery or pathology from May 2009 to September 2012 were analyzed retrospectively. The accuracy of MRI was analyzed. Results 18 cases of pituitary adenoma, craniopharyngioma in 10 cases, 9 cases of meningioma, epidermoid cyst in 4 cases, germ cell tumor in 2 cases, all kinds of tumors have their own specific MRI imaging features. Conclusion MRI can correctly display the suprasellar tumor and its adjacent anatomical structures. It can distinguish the different characteristics of the suprasellar tumor signals and is very helpful to the diagnosis of tumors.
