脊髓内室管膜瘤的MRI表现

MRI Features of Spinal Ependymoma

目的探讨脊髓内室管膜瘤的MRI表现,以提高对本病的诊断正确率。方法回顾性分析经手术病理证实的脊髓内室管膜瘤10例,分析肿瘤部位、信号特点及肿瘤强化特点。结果肿瘤位于颈髓5例,胸髓3例.终丝及马尾2例.在T1WI上呈等、低信号,在T2WI上呈等、高信号。10例均出现不同程度强化。结论脊髓内室管膜瘤MRI表现具有一定特征性,结合其发病部位、信号特点、强化特点及临床资料常可作出正确诊断。

Objective To study the MRI features of spinal ependymoma and to improve the accuracy of diagnosis of the disease. Methods To Retrospectively analyze 10 cases of the spinal cord ependymoma confirmed by operation and pathology with tumor location, signal characteristics and tumor enhancement features. Results The tumors were located in the cervical spinal cord for 5 cases, in the thoracic spinal cord for 3 cases, and in the filum terminale and cauda equina for 2 cases. These tumors appeared low signal on T1 WI, high signal on T2 WI, and different degrees of enhancement occurred for 10 cases. Conclusion Spinal cord ependymoma has characteristic MRI appearances, we can make a correct diagnosis of the disease combined with its location, signal characteristics, the strengthen characteristics and clinical data.
