This report describes a case of split cord malformation without a septum. A 2-year-old boy presented with a 3-month history of neurogenic bladder. MRI did not show any apparent abnormality around the conus medullaris. However, CT myelography clearly demonstrated the presence of a split filum terminale. The patient underwent laminectomy of L1-5 laminas and untethering of the split filum terminale. CT myelography was superior to MRI in diagnosing split cord malformation in this case. As MRI is currently regarded as the superior imaging modality, this reported case may have been missed because the pathology was not apparent on MRI.
本报告描述了一例无中隔的脊髓纵裂畸形病例。一名2岁男孩有3个月神经源性膀胱病史。磁共振成像（MRI）未显示圆锥马尾周围有任何明显异常。然而，CT脊髓造影清楚地显示了终丝分裂的存在。患者接受了L1 - 5椎板切除术和终丝分裂松解术。在该病例中，CT脊髓造影在诊断脊髓纵裂畸形方面优于MRI。由于目前MRI被认为是 superior imaging modality，该报告病例可能因MRI上病理表现不明显而被漏诊。 （注：“superior imaging modality”这里直接保留英文未翻译，因为不清楚其准确的中文术语，可能是“高级成像方式”之类的表述，需结合更专业背景确定准确翻译）
