目的 探讨脊髓畸胎瘤的影像诊断。方法 分析 10例脊髓畸胎瘤的临床和影像表现。髓内 8例 ,髓外 2例。全部病例均作MR扫描。结果 5例腰段 ,3例胸段 ,1例胸腰段 ,1例颈段。 7例多囊腔 ,3例单囊腔。MR显示肿瘤呈混杂信号 ,T1WI脂肪抑制增强扫描后病灶内脂肪信号消失 ,肿瘤部分不均匀强化。 3例腰段脊髓畸胎瘤伴有脊髓低位。结论 脊髓畸胎瘤MR表现具有特征性 ,MR的T1WI脂肪抑制增强扫描是正确诊断脊髓畸胎瘤最有效的方法
Objective To investigate the imaging diagnosis of spinal teratoma. Methods The clinical and imaging findings of 10 cases of spinal teratoma were analyzed. 8 cases of intramedullary, extramedullary in 2 cases. All cases were MR scan. Results 5 cases of lumbar, 3 cases of thoracic, 1 case of thoracolumbar, 1 case of cervical segment. 7 cases of multi-cystic cavity, 3 cases of single cyst. MR showed tumor was mixed signal, T1WI fat suppression enhancement of the lesion fat signal disappeared, the tumor part of the uneven enhancement. 3 cases of lumbar spinal cord teratoma with spinal cord low. Conclusions MR appearance of spinal teratoma is characteristic. MR T1WI fat suppression enhanced scan is the most effective method for the correct diagnosis of spinal teratoma
