髓内神经鞘瘤1例报告并文献复习

目的:探讨髓内神经鞘瘤的临床表现、起源、影像学表现及鉴别诊断。方法:回顾性分析经手术病理证实的颈髓髓内神经鞘瘤的MRI表现及文献复习。结果:髓内神经鞘瘤好发于颈髓,T1WI呈等或稍低信号,T2WI呈等或稍高信号,信号多均匀,边界清楚,可伴有脊髓水肿和脊髓空洞,增强扫描肿瘤明显均匀强化。结论:髓内神经鞘瘤的影像学表现具有一定的特征性,诊断需结合病理学和免疫组化检查。

Intramedullary schwannoma: a case report and literature review

Objective: To investigate the clinical character,origin,imaging manifestation,and differential diagnosis of intramedullary schwannoma of the central nervous system.Methods: One case of cervical spinal cord intramedullary schwannoma proved by pathology was analysed retrospectively,and the relative literature was reviewed.Results: Intramedullary schwannoma is seen most in cervical spinal cords.MRI showed isointensities or slightly lower intensities on T1 weighted images,and showed isointensities and slightly higher intensities on T2 weighted images.The tumor displayed a homogeneous intensities and clear borders,which accompanied spinal cord edema and spinal cord cavity disease.In the enhanced scans,there was apparent enhancement of the solid parts of tumors.Conclusion: Imaging manifestation of intramedullary schwannoma of the central nervous system has some characteristics,but it still relies on pathology and immunohistochemistry to make a definite diagonosis.
