Two cases are reported of Arnold-Chiari type I malformation associated with syringomyelia, in which magnetic resonance (MR) imaging revealed spontaneous decompression of the syrinx. In one case axial MR imaging sections showed a communication between the syrinx and the spinal subarachnoid space, which supports the hypothesis that fissuring of the cord parenchyma is instrumental in the spontaneous resolution of syringomyelia. The MR imaging changes were not accompanied by variations in the patients' clinical course.
报告了两例与脊髓空洞症相关的Ⅰ型阿诺德-奇亚里畸形病例，其中磁共振成像显示脊髓空洞症自发减压。在一例中，轴向磁共振成像切片显示脊髓空洞与脊髓蛛网膜下腔相通，这支持了脊髓实质裂开有助于脊髓空洞症自发消退的假说。磁共振成像的变化并未伴随患者临床病程的改变。
