目的:探讨磁共振成像对颈部神经源肿瘤的定位、定性诊断价值。方法:回顾性分析经手术及病理证实的颈部神经源肿瘤的磁共振成像31例,包括神经鞘瘤23例,神经纤维瘤7例,恶性神经源肿瘤1例。结果:依据肿瘤引起的附近间隙、血管、肌肉等移位方向进行肿瘤定位。神经鞘瘤病理上有不同组成成分,因此可根据磁共振的信号特点及增强后表现对其作出定性判断。结论:磁共振成像是诊断颈部神经源肿瘤的有效方法,最有价值的诊断指征为肿瘤的部位、肿瘤与邻近结构的关系以及肿瘤的信号变化。
Objective: To investigate the localization and qualitative diagnosis of cervical neurogenic tumors by magnetic resonance imaging. Methods: A retrospective analysis of 31 cases of surgically and pathologically confirmed cervical neurogenic tumors, including 23 schwannoma, 7 neurofibroma and 1 malignant neurogenic tumor. Results: According to the tumor caused by the nearby gap, blood vessels, muscles and other shift direction for tumor location. Schwannoma pathology has different components, it can be based on magnetic resonance signal characteristics and enhance the performance of its qualitative judgments. Conclusion: Magnetic resonance imaging is an effective method to diagnose cervical neurogenic tumors. The most valuable diagnostic indications are the location of the tumor, the relationship between the tumor and adjacent structures, and the signal changes of the tumor.
