We report the assessment by MRI of a case of radiculomyelitis after vaccination against tetanus-poliomyelitis. In the acute stage the appearance was an isolated myelitis of the conus medullaris with contrast enhancement. The upper thoracic cord presented central areas of high signal intensity on T2 weighted images. Rapid clinical recovery was correlated with resolution of abnormal enhancement. Follow-up MR at 5 months showed persistence of slight T2 prolongation in the conus medullaris and syringohydromyela of the thoracic cord. A single lesion of the spinal cord is a rare presentation of acute disseminated encephalomyelitis, the course of such lesions, to date not previously displayed by MR, is unknown. Proper diagnosis should help prevent administration of further vaccine doses.
我们报告了1例破伤风-脊髓灰质炎疫苗接种后神经根脊髓炎病例的MRI评估结果。急性期表现为圆锥孤立性脊髓炎伴强化。胸髓上段在T2加权像上呈现中央高信号区。临床快速恢复与异常强化的消退相关。5个月后的随访MRI显示圆锥轻微T2延长及胸段脊髓空洞症持续存在。脊髓单发病变是急性播散性脑脊髓炎的罕见表现，此类病变的病程此前未被MRI显示过，目前尚不清楚。正确诊断有助于避免进一步接种疫苗。
