摘要
目的:提高对放射性脊髓损伤的认识与诊断水平。方法:3例为肺癌,1例为食管癌的患者,在用钴- 6 0或加速器放射治疗后6个月到5年间出现双下肢进行性肌力减弱及节断性感觉异常来复诊,经过体格检查诊断为放射性脊髓损伤,而行脑脊液生化,胸段脊髓CT和MRI检查。结果:损伤平面以下脑脊液压力增高,淋巴细胞和蛋白含量增高。CT检查仅有皮肤及皮下组织变薄。MRI检查除CT可见外,放射野内损伤的脊髓呈稍长或长T1,长T2信号,注射Gd -DTPA后,病变不同程度强化。结论:查体,病史及核磁检查是诊断放射性脊髓损伤的主要方法。
Objective:To improve diagnosis and treatment of radioactive injury of apinal cord.Methods:CT,MRI examination of thoracic spine and brain-spine liquid test were performed in 3 pulmonary carcinoma and 1 esophageal carcinoma after radiotherapy from six months to four years.Results:Injury of spinal cord lever were correspond with radiation fields and the skin like leather in physical examination,the content of protein in brain-spine liquid increased,the subcutaneous tissue and skin were thinning in CT,MRI findings showed the lesions limited in the radiation fields,and slightly long T1 and long T2 signal.After injection with Ge-DTPA,image of lesions showed different levels of intensification.Conclusions:Physical examinations case history and MRI in radioactive injury of spinal cord.
