马尾肿瘤的MRI诊断

The MRI Diagnosis of Cauda Equina Tumor

目的分析马尾肿瘤MRI的诊断特点。方法选择我院15例马尾肿瘤患者全部行MRI检查,其中男9例,女6例,14例经手术治疗。结果病理诊断15例马尾肿瘤中,神经纤维瘤8例,皮样囊肿和表皮样囊肿3例,脂肪瘤2例,室管膜瘤1例,转移瘤1例。术前MRI诊断与术后病理诊断基本相符。结论MRI对马尾肿瘤的诊断可靠,为临床的手术治疗提供了正确的病变分析。

Objective 15 cases of cauda equina tumor were reported. Their clinical and MRI characteristics were discussed. Methods All of these 15 cases, including 10 males and 5 females, were examined with MRI. 14 of them were treated with surgical resection. Results The pathological diagnoses of these 15 cases of cauda equina tumor revealed that there were 8 cases of neurofribroma, 3 cases of dermoid cyst and epidermoid cyst, 2 cases of lipoma, 1 case of ependyma tumor and 1 case of metastasis. The MRI diagnoses were consistent with the results of surgical diagnoses. Conclusion By providing accurate pathological diagnoses for the clinical surgery, the MRI was confirmed to be a very reliable method for cauda equina tumor diagnosis.
