Abstract
The authors present the initial and follow-up MR findings in a patient with subacute combined degeneration of the spinal cord, a complication of vitamin B12 deficiency, and a rare cause of demyelination of the dorsal and lateral columns of the spinal cord. Initial study showed high intensity in the dorsal columns of the cervical and thoracic spinal cord on T2-weighted image. Five months after treatment, the abnormal signal intensity was noted to have decreased.
摘要
作者展示了一名脊髓亚急性联合变性患者的初始及随访磁共振成像（MR）结果。脊髓亚急性联合变性是维生素B12缺乏的一种并发症，也是脊髓背侧和外侧柱脱髓鞘的罕见原因。初始研究显示，在T2加权图像上，颈段和胸段脊髓的背侧柱呈高信号强度。治疗五个月后，发现异常信号强度有所降低。
