摘要
目的探讨神经纤维瘤病Ⅱ型(NF-Ⅱ)的MRI表现,提高对本病的认识。方法收集8例经临床及病理证实的NF-Ⅱ患者的临床资料进行分析总结。结果双侧听神经瘤6例,其中合并多发脑膜瘤4例,多发神经鞘瘤2例;脊膜瘤并侧脑室室管膜瘤1例;一侧听神经瘤合并枕颈部皮下神经纤维瘤,合并多发脑膜瘤1例。结论MRI是检查NF-Ⅱ中枢神经系统病变理想的影像学检查方法,可较好的显示其多发性及多灶性病变。
Objective To investigate the MRI findings of neurofibromatosis- lI and improve diagnosis of the disease. Methods The clinical data and MR feathures of 8 patients with neurofibromatosis-Ⅱ were analyzed retrospectively. Conventional MR plain scan and enhanced scan were performed in all patients. Results Six cases with bilateral acoustic neuroma, in which 4 cases combined with multiple meningioma, 2 cases with multiple schwannoma; 1 case with meningioma and lateral ventricle ependymoma; 1 case with acoustic neuroma and pillow neck subcutaneous neurofibromas and multiple meningioma. Conclusions MR can show the shape and signal features of neurofibromatosis- Ⅱ lesions and there-fore it has an important value for detecting the lesions in CNS whereas enhanced scan is helpful to show the lesions missed on plain scan.
