| 中文摘要: |
| 目的探讨软组织神经源性肿瘤MRI 的诊断价值。方法分析26 例由病理证实的软组织神经源性肿
瘤MRI 表现,并与病理比较。结果神经鞘瘤11 例,神经纤维瘤7 例,节细胞神经瘤1 例,神经纤维瘤病1 例,恶性
神经鞘瘤4 例和神经纤维肉瘤2 例。26 例中21 例与神经血管束伴行(占80.8 %) ;3 例神经纤维瘤出现“靶征”;5 例
出现肿瘤邻近或远端肢体肌萎缩。结论综合分析肿瘤的部位、形态、信号及其邻近的神经血管束,有助于确立软
组织神经源性肿瘤的诊断,但MRI 对其良、恶性的鉴别有较大局限性。 |

| Objective To investigate the diagnostic value of MRI in neurogenic tumor of soft tissue. Methods The
MRI manifestations of twenty-six neurogenic tumors confirmed pathologically were analyzed in comparison with the patho-
logic findings. Results The study population consisted of 11 schwannomas , 7 neurofibromas , 1 ganglioneuroma ,
1neurofibromatosis ,4 malignant schwannomas and 2 neurofibrosarcomas. Of 26 cases ,twenty-ne tumors were accompanied
closely with the adjacent neurovascular bundles (80. 8 %) ,and 3 neurofibromas showed ”target sign”. And the atrophy of
muscles in the nearby or distal part of limb due to the tumor occurred in 5 cases. Conclusion Analyzing comprehensively
the location , shape ,signal features and adjoining neurovascular bundles of the tumor is very conducive to establishing the di-
agnosis of neurogenic tumor in soft tissue ,while the capability of MRI to distinguish the benignity and malignancy is much
limited. |
