A holocord syringomyelia due to Chiari 1.5 malformation (CM) in a 12-year-old girl was serially imaged with 3 T MRI over 4 years. The serial MRI showed reduction in size of the syrinx, without any surgical intervention or CM improvement, but rather due to spontaneous spinal cord tear. The tear was clearly demonstrated by evidence of flow signal across the tear between syrinx and subarachnoid space at the upper thoracic level. The tear showed spontaneous closure at follow-up. A medullary tear has been described in the adult population as one of the putative causes of spontaneous syringomyelia reduction, but its clear demonstration with modern high-resolution MRI has not been reported in the paediatric population. Moreover, this is the first reported case of syrinx reduction due to spontaneous fissuration in a paediatric patient.
12 岁女孩因 Chiari 1.5 畸形（CM）导致全脊髓空洞症，4 年间连续接受 3T MRI 成像。连续 MRI 显示脊髓空洞缩小，无任何手术干预或 CM 改善，但由于自发性脊髓撕裂。撕裂通过在胸段上部蛛网膜下腔和脊髓空洞之间的撕裂处显示的血流信号证据得到明确证实。撕裂在随访时自行闭合。髓内撕裂已在成年人群中被描述为自发性脊髓空洞缩小的潜在原因之一，但在儿科人群中尚未有明确显示其与现代高分辨率 MRI 的关系的报道。此外，这是首例报道的因小儿患者自发性裂孔导致脊髓空洞缩小的病例。
